Voronoi Upgrades for Modular Candy Dispenser 

Voronoi Upgrades for Modular Candy Dispenser Display Only Do Not Print.stl

Set up your candy dispenser just the way you want it!

See here for video: https://youtu.be/759B56bt7HI   

This set contains options for bases, push-button cartridges, and candy reservoirs. Everything is interchangeable. It is sized specifically for "Gobstoppers" which are between 13-14 mm in diameter. The holes are 15 mm to allow for extra clearance.

Bases

If you want all the candies to come out on the same side, print "Base Single Side." If you want to have candy coming out both sides, print "Base Double Side."

Push-button Cartridges

If you want the candy to come out on the same side as the button, print the "Self Serve" cartridges. If you want the candy to come out on the opposite side, print the "Guest Serve" cartridges. You will need to print out both the "left" and "right" for each cartridge.

You will need three cartridges to fit into the bases provided. If you want fewer than three cartridges, simply use one of the single reservoirs as a spacer (and to store extra candy!)

Print a “Spring” and “Button” for each cartridge.

Candy Reservoirs

Choose if you want a separate “Single” candy reservoir for each button cartridge, or a large “Full” reservoir that feeds into all of the button cartridges. 

Files are provided for standard or spiralized printing. The spiralized models are optimized for a .8mm nozzle, but other sizes will work.

If you are printing three “Single” reservoirs, you will also need a “Connector” to hold them on the button cartridges, and a “Top Cap” to secure the tops together.

These interconnecting “tube-like” pieces offer a tactile way to explore and discover the geometry of the 12-sided dodecahedron and 20-sided icosahedron, two dual Platonic polyhedra. See video here: https://youtu.be/SR5kkRHFiGo 

Pieces snap together at a 90-degree angle. The connecting surfaces of the “Penta Tube” align with the edges of a regular pentagon. The angles of the connecting surfaces of the “Dihedral Tube” are derived from the dihedral angle of the dodecahedron, that is, the angle between two adjacent faces of a dodecahedron. The “End Cap” is an aesthetic option for putting on unused ends.

The primary structure that can be made using these pieces is a basic dodecahedron using 12 “Penta Tubes” and 30 “Dihedral Tubes.” This is the spherical structure pictured above. The “Penta Tubes” become the faces of the dodecahedron, while the “Dihedral Tube” is oriented orthogonal to the edge of the dodecahedron and holds adjacent faces at the proper dihedral angle.

Try changing the orientation and positioning of the pieces and you’ll discover even more polyhedra based on the dodecahedron and icosahedron.

You could use them to hold other things, but really, they’re designed for eggs.

See here for video: https://youtu.be/zt_lCCp3u7g 

These playful egg holders are designed using a process call “topology optimization.” Topology optimization is a mathematical design method that optimizes material layout within a given design space, for a given set of loads, boundary conditions and constraints with the goal of maximizing the performance of the system. 

These designs were made using nTopology.

The ten models are made unique by randomizing the load points on the egg surface. You can further differentiate multiple prints by slightly scaling them along the z axis to add some variability in height.

Inputs to the topology optimization process used a theoretical 100kg egg placed on a titanium alloy pedestal.

This puzzle is based on the “Weaire–Phelan structure,” the most mathematically efficient way for equal-volume bubbles to fit together to make foam. 

See here for video: https://youtu.be/f0dXaUWX-HY

The complete puzzle requires 18 pieces. Ideally, I recommend printing out 16 “Weaire Phelan Tetrastix” pieces and 2 “Weaire Phelan Tetrastix Key” pieces. The “key” pieces have some of the face trimmed back to make it easier to insert them as the final two pieces. If you have difficulty assembling this combination, try using 14 “Weaire Phelan Tetrastix” and 4 “Weaire Phelan Tetrastix Key” pieces.

The Weaire–Phelan structure is made up of two pentagonal dodecahedra (12-sided) and six tetrakaidecahedra (14-sided) that form a translation unit with a lattice periodicity which is simple cubic.

The pieces in this puzzle are each made of six tetrakaidecahedra stacked face to face. The holes inside the complete puzzle are in the shape of the pentagonal dodecahedra.

There is a good introduction to the “Weaire–Phelan structure” here: http://www.steelpillow.com/polyhedra/wp/wp.html 

Here is some information on “Tetrastix”: https://en.wikipedia.org/wiki/Tetrastix

I uncovered this strange artifact in my garden the other day. What is it? And why do I love it so much?

See here for video: https://youtu.be/nGdtFcfjxc0

I wish I could offer instructions for assembly. I found it and managed to disassembly it, but I have no idea how it goes back together. Maybe you can help?

The red outer body is covered in randomly placed protrusions, each of which contains a blue, oval-shaped piston of sorts.

Rotating the bottom plate makes the blue pistons move in and out. There seems to be some sort of pattern in the movement, but I can’t figure out what it was supposed to do.

I managed to unscrew the bottom and pulled out a stack of offset circular cams that must have been driving the movement of the pistons. I am not sure I can put it back together.

I’m going to send it off to the folks at the Elgreen Project (http://www.elgreenproject.com/) , maybe they’ll recognize it.

Do you know what it is? Do you know what it was used for?

A “Cabochon” is a gemstone that has been shaped and polished, as opposed to faceted.

See here for video: https://youtu.be/5xajyMzhHXw

The “gemstones” in these bracelets are captive, meaning that once printed they rotate freely within the band. 

This design is particularly suited to printing with multicolour filament as rotating the gemstones allows for visualization of the different filament colours.

Once printed, allow the print to cool. Wiggle each gem back and forth until it breaks from the small internal supports.  Twist it a few times until it turns smoothly.

Setting your “Z Seam Alignment” to “Random” will prevent a visible seam on the contoured surface of the “gemstone.”

The inner diameter of each bracelet is as follows:
24 Gemstones: 90mm
20 Gemstones: 75mm
16 Gemstones: 60mm

Make up your own fortunes for these reusable fortune cookies!

See here for video: https://youtu.be/iJyJzYAkdGg 

To insert an object or large piece of paper, you will need to pause the print at the right time, insert your object, and resume print.

Smaller pieces of folded paper can be inserted through the crack after the print is finished. It is best to fold the paper up so that it expands inside and doesn’t fall back out.

To reuse, simply add a new fortune and close back up with a small dab of glue to keep it shut.


Reuseable Fortune Cookie

This print-in-place chess set prints with board and all 32 pieces in a single print.

The pieces are separate objects but are held captive within the board and move along notches during game play. Because the pieces are held captive, the board could be used as a travel chess set.

Use paint to darken the appropriate square and pieces. The pieces can be removed and reinserted by pushing against the back of the board to splay the notches apart.

The board is 204.2 mm square. The bottom is thin to reduce material, so you’ll need to monitor the first layer closely and restart if there are any errors. The build plate needs to be perfectly level and calibrated.

Files include the full board and pieces, separate pieces in case you need to replace any, and a board structure without pieces if you want to add your own.

Game play remains the same but instead of moving in straight lines, pieces move in arcs across the negative Gaussian curvature of a hyperbolic paraboloid. Also, the board rocks back and forth, which might be a bit distracting!

Magnets are required to hold the pieces in place unless you are playing in a non-Euclidean universe.  

For the board, print two of the “Hyperbolic Paraboloid Half Board” files. You won’t need supports, but brim is recommended. Glue the bottom edges together.

Before printing the squares, decide if you want the board to be oriented so that players face each other from “hilltops” across a valley, or from “valleys” up over a ridge. The board needs to be oriented such that each player has a white square in the lower right corner. 

The files provided here are named for the “Hill to Hill” orientation, as if your white pieces are on the hill closest to you facing black across the board on the opposite hill. When printing out the quadrants, it is important to not let them get mixed up or it will be next to impossible to sort them out again. 

You will need to print out one copy of each of the “Quadrant” file for each half of the board. Combine the “Hill to Hill Left Quadrant White” with the “Hill to Hill Left Quadrant Black” and arrange them according to the reference dimples described below. Print “Hill to Hill Right Quadrant White” and “Hill to Hill Right Quadrant Black” and combine them in the same way. Do this for both sides of the board.

Proper positioning of the “square” tiles on the board framework is the most challenging part of assembly. The pieces all have very subtle differences in curves and edge lengths, and it is easy to put them in incorrectly. To make this easier, small reference dimples have been added to the bottoms of each “square” tile. There is a single dimple on the corner of the tile that is most oriented towards the center of the board. There is a single dimple towards the outer side of the four inner “squares,” and two dimples towards the outer side of the outer twelve “squares.” Refer to the picture provided.

Arrange the pieces first and inspect the contours of the top of each piece to ensure that the directions of concavity and convexity makes sense according the where the piece is on the board.

A standard set of playing pieces is included with holes for 1/8” by 1/8” magnets. 

You will need a total of 96 1/8” by 1/8” magnets, one for each square and one for each piece. Insert the magnets into the square tiles before gluing them on to the frame. Make sure you get the polarity right so that all the pieces stick to all the squares! The magnets used in the design and assembly of this model were purchased through www.kjmagnetics.com. 

Once you’ve inserted the magnets and determined the correct orientation of each piece, go ahead and glue them in place. CA glue works well.


Hyperbolic Paraboloid Chess Board

Hyperbolic Paraboloid Display Do Not Print.stl

This “Wormhole Chess Board” is composed of two back-to-back regular sized chess boards connected by a catenoid surface through the central 4 x 4 grid of squares on each board.

See here for video: https://youtu.be/ohfqQ_8oEoY 

Actual game play on this board is beyond challenging so unless you’re a genius, this board is more of an art or conversation piece.

Part of what makes game play so challenging is the presence of the eight pentagons that are required to transition between the flat and curved surfaces. 

Here are a few suggestions if you want to try playing. 

Moving a piece through a pentagon allows for additional movement options. When entering from a column or row on the flat surface (such as with a rook) there are two exit options, one that allows the piece to remain on the flat surface and another that allows the piece to enter the wormhole. The reverse is true when entering a pentagon from the wormhole. When entering a pentagon from a diagonal (such as with a bishop) there are two options for exiting the pentagon, both of which allow the piece to remain on its own colour. 

Because this piece is essentially two chess boards, there are four possible ends from which to start your pieces. 

For a two-player game, each player could use a single set or pieces each and leave two ends empty. Alternatively, each player could have two sets of pieces facing each other across the flat surface as well as through the catenoid surface. This means that there would be two kings, which would complicate the end game somewhat!

Another option would be to play as a four-player game with each set of pieces a different colour.

If anyone comes up with a comprehensive set of rules for incorporating the pentagons into game play, please share them! 

Here are printing and assembly instructions:

For the board, print two of each of the “Flat Board Half” and “Wormhole Half” files. No supports needed. Glue together carefully.

For the squares, you will need a total of 4 “Quadrant of Squares” for each colour. Note that there are small reference dimples on the bottom of the curved pieces. When properly positioned, the dimples will point towards the pentagonal piece.

Two standard sets of playing pieces are included, each with holes for 1/8” by 1/8” magnets. The larger size looks better, but pieces may collide when passing through the wormhole. Pieces in the smaller set won’t collide while passing through the wormhole.

You will need a total of 208 1/8” cylindrical magnets, one for each board piece and each playing piece (assuming you’re using two full sets of playing pieces). This model uses 1/8” length magnets, but 1/16” length would probably work fine. 

Insert the magnets into the square tiles before gluing them on to the frame. Make sure you get the polarity right so that all the pieces stick to all the squares! The magnets used in the design and assembly of this model were purchased through www.kjmagnetics.com. 

Once you’ve inserted the magnets and determined the correct orientation of each piece, go ahead and glue them in place. CA glue works well.

The “Spherical Chess Board Frame” is provided with and without supports. The version with supports provides extra stability around the base of the pillars when printing. You will still need to add your preferred support for the rest of the structure, but you’ll need less of it. 

You will need a total of four “Tile Quadrants,” two of each colour. 

A standard set of playing pieces is included with holes for 1/8” by 1/8” magnets. 

You will need a total of 96 1/8” by 1/8” magnets, one for each square and one for each piece. Insert the magnets into the square tiles before gluing them on to the frame. The magnets used in the design and assembly of this model were purchased through www.kjmagnetics.com. 

Proper positioning of the “square” tiles on the board framework is the most challenging part of assembly. There are a few pieces that have very subtle differences in curves and edge lengths, and it is easy to put them in incorrectly. To make this easier, small dimples have been added to the bottoms of each “square” tile. There is a single dimple on the uppermost corner of every tile to ensure proper orientation. There is a single dimple on the outer chamfer of the four inner “squares,” and two dimples on the outer chamfer of the outer twelve “squares.” Refer to the picture provided.

Arrange the piece first, do a dry fit to make sure you’ve got it right, then use glue to attach the tiles to the framework. CA glue works well.

The magnet holes on the pieces and tiles are designed for a tight fit and shouldn’t need glue. Make sure you get the polarity right so that all the pieces stick to all the squares!

Do not print these files directly! These files are intended to be assembled digitally and then printed all at once as a “print-in-place” model.

This snake uses a unique print-in-place ovoid joint designed to be stronger than the interlocking double ring joints used in many articulated designs, so this design is more suitable for use as a fidget or children’s toy.

You will need some experience with stl editing software to digitally assemble and prepare this snake to print. Meshmixer is a free and suitable program, but there are many others.

Here is a suggested workflow:

1.	You will need to reference the origin point in your software in order to manipulate these files. Ensure that you know how to move and rotate objects relative to the origin point.
2.	Import the “Head” and either the “Tail Pieces Curved” or “Tail Pieces Straight”. “Tail Pieces Curved” will save you a bit of space, especially if you are planning on coiling the snake to print.
3.	Import the letter segments that you will need to write your word or message.
4.	The snake is assembled by progressively adding letters to either the head or tail and applying rotation and translation along the x axis.
5.	Move the assembled pieces exactly 25mm to position them properly relative to the next piece.
6.	You may add rotation between pieces as you assemble them, but no more than 18 degrees or you will begin to get adhesions when printing.
7.	Once you have your snake digitally assembled, run it through your preferred slicer and print! You may get some small adhesions between segments. Simply apply a bit of force to move the joint the first time, and it will be fine after that.

Please feel free to contact me if you get stuck or would like help making a custom snake!

The 600-cell is one of six regular convex four-dimensional shapes. It is composed of 600 tetrahedral cells.

The full 600-cell is so ridiculously complex that it nearly impossible to see or understand in its entirety, so it is helpful to view it in parts.

If you look closely at this selection of cells, you can see how it is composed of nine interlocking rings connected by “struts.”  In the full 600-cell, these small “struts” are in fact part of complete rings. This gives some idea of how large and complex the full shape would be.

Triply Periodic Minimal Surfaces (TPMS) are mathematically intriguing and aesthetically beautiful. Unfortunately, they are also difficult to make. This collection contains three different formats each of twelve triply periodic minimal surfaces that you can use to remix into your own math art designs.

See here for video: https://youtu.be/tMqM8IVBq7Q 

Unit Cell (thickened): These unit cells have been thickened to approximately 2.4mm. They print well on a resin printer, and most can be printed on an FDM printer as well. 

Unit Cell (surface): These unit cells are surfaces only and cannot be printed directly. They must be imported into an stl editing software such as Meshmixer to thicken, pattern, or modify as you like.

100mm x 100mm x 100mm cube: These cubes contain a matrix of tiled unit cells. They are surfaces only and cannot be printed directly. They can be sliced into different shapes and then thickened into printable models.

The following surfaces are included:

Schwarz’ P, Schwarz’ D, Schoen’s Gyroid, Schoen's Batwing, Fischer-Koch S, Schwarz’ CLP, Schoen’s I-WP, Schoen’s F-RD, Schoen’s F-RD(r), Fischer-Koch C(Y), SplitP and Neovius.

The SplitP and Neovius were formed using nTopology. The remaining surface were desinged in CAD using this resource: http://facstaff.susqu.edu/brakke/evolver/examples/periodic/periodic.html

“Reticular” forms are characterized by a fine network or netlike structure. The most common anatomical example is the reticular formation in the brain, one of the oldest parts of the brain that plays a crucial role in consciousness.

When designing these pieces, I imagined what it would be like to inhabit and move around inside of these shapes. 

To add a dash of function, the forms have a hole at the top that can be used to hold your favourite organic plant material. The 26mm diameter hole will also hold a 1” test tube or similar container for water.

To add a dash of function, the forms have a hole at the top that can be used to hold your favourite organic plant material. The 26mm diameter hole will also hold a 1” test tube or similar container for water.

The hull and walls of this Benchy are built with face-centered cubic lattice structure. Great to show off your resin printer, but not very seaworthy.

See here for video: https://youtu.be/JXszXspeMn4

As is, the model is approximately 100mm in length and the lattice structures are 1mm diameter. The model scales well if you need to make the lattice structures more visible.

These hangers have a built-in rotating label to seriously up your closet organization game.

Use the “Weekday Dial” to lay out your weekly wardrobe ahead of time.

Use the “Season Dial” to make sure you don’t end up wearing your sweater in middle of summer.

Don’t wash your shirt every day? Use the “Wear Tracking Dial” to record number of wears. Safer than the sniff test.

Want to make fun of your dad’s wardrobe? The “Style Dial” let you indicate if a shirt is “In style,” Not in style,” or “Missing a button.” 

Print “Dial Hook,” “Standard Frame 1,” and “Standard Frame 2.” Snap together as shown in the video. Print your selected dial. Pinch the dial to snap it into place.

These pieces snap together to form a spherical truncated icosahedron, a shape recognizable as a football or soccer ball. 

See here for video: https://youtu.be/C-KsbcPzaH4 

In the model shown, the “Penta” pieces are printed in black, the “Hex” pieces are printed in white. A complete ball requires 20 of the “Hex” pieces and 12 of the “Penta” pieces. The files provided will create a ball that is 100mm in diameter.

This design minimizes that amount of material needed to print large spheres, and also allows for multicolour balls by printing pieces in different colours.  You do not need supports to print, but you will need to ensure good bed adhesion. 

The pieces hold together on their own and will not need glue.

When assembling, be aware that the connection tabs on the hexagonal pieces are different depending on whether that side is connecting to another hexagonal piece or a pentagonal piece.

Pentagonal pieces only ever connect to hexagonal pieces, so the pentagonal tabs are all the same.

The tolerance between pieces is intentionally tight and will require some force to assemble. You can loosen the fit by filing of the thicker bottom layer “elephant foot” on each piece, or by scaling up the pieces slightly to increase the space between.  Be sure to do a few small test prints first before printing a whole batch.

This art project is a response to the May 2022 report by Amnesty International that found and documented evidence of war crimes committed by Russian troops during the invasion of Ukraine. 

It is a reflection on breath, bodies, and the fragility of international agreements such as the UN Declaration of Human Rights.

See here for video: https://youtu.be/R9MA7xIS0kQ 

This is an advanced project to print and prepare.

Printing

Files should be printed with a 0.4mm nozzle in order for text to be properly printed. Try to position objects with text facing up or to the side so that the text does not create any overhangs. Overall, some of the objects will need a large amount of support.

Printed pieces will likely need some sanding and smoothing.

Preparing

The parts in the model pictured are connected by two twists strands of 20-gauge wire anchored in place with CA glue. 

Achieving proper relative placement of the bones is important. One way to determine the required lengths of wires is to import the “Display Only” file in to an stl editing program like Meshmixer and measure the distance between points.

Display

You are welcome to print, assemble and display this art piece for free. While the piece arose from the specific context outlined above, its message is relevant to a range of social justice and human rights issues.

This snap-together modular strut system can be used to create large scale 3D printed objects with minimal time and material. Chairs? Tables? Bridges? How big will you go?!

See here for video of some basic shapes and structures: https://youtu.be/ifpAeNatWeI 

The “octet truss” is a geometric pattern used in architecture and structural engineering in the design of lightweight, rigid space frames used to span large areas or fill large spaces. It is known for being strong, rigid, and lightweight.

The 3D printing technique known as “spiralized printing” or “vase mode” is faster and uses relatively less material than other slicing techniques.

This design combines the geometry of the octet truss with a shape that is optimized for spiralized printing. In “Spiralized Mode,” a single piece will print in 20 min at regular speed and use less than 4g of material. In comparison, printing a single piece in regular non-spiralized settings takes approximately 35min and 12g of material.

The octet truss is composed of tetrahedrons and octahedrons with twelve struts joining at each vertex. The pattern is quite instinctive once you start playing with the pieces, so you do not need to understand the geometry to build with this design. This lattice structure can continue infinitely to take on whatever structural shape you would like to create.

The pieces to require some force and a bit of practice to snap together. They are held in place by the flexible nature of the spiralized print. Assembled pieces are actually quite strong on their own, but you can add glue for a stronger and more permanent structure.

The strut dimensions will allow for multiple “one at a time” prints in spiralize mode. This takes a bit more time to set up but allows for up to 12 prints on a 220mm x 220mm print bed. It is also fun to watch!

There are two “end caps” and a “patch piece” to use depending on what orientation of the struts define the outer boundary of your end form. Ends caps and the patch piece are printed in standard settings, NOT spiralized!

The “Half Cap” is used in combination with two “Patch Pieces” to create a flat surface where five struts come together. The “Quarter Cap” is to create a flat surface on an incomplete vertex where eight struts come together. Different combinations of caps and patches can be used to cap off a variety of surface and edge requirements. This sounds complicated, but the best way to figure it out is just to start playing with the pieces!

Stay tuned for an instructional video on the use of the caps and patches.

The struts are designed to print with a 0.8mm nozzle. They will print with a smaller nozzle but may not be as strong. Here are recommendations for printing in Cura:

1.	Turn off bottom layer by setting “Top/Bottom Thickness” to 0mm
2.	Adding a “skirt” is a good idea
3.	In “Special Modes,” check “Spiralize Outer Contour.”
4.	To print multiple copies in one print, go to “Special Modes” and change “Print Sequence” to “One at a time”. If you choose this option, you will need to pay special attention to placing the objects on the print bed in such a way that the print head and gantry do not collide with the finished prints. The files is sized to allow 12 “one at a time” prints on a 220mm x 220mm Ultimaker 2+ print bed.

Stay tuned for more projects based on this design!

This snake uses a unique print-in-place ovoid joint designed to be stronger than the interlocking double ring joints used in many articulated designs, so this design is more suitable for use as a fidget or children’s toy.

Like a “ball and socket” joint, the oval-shaped ovoid from one segment is held in place by a similarly shaped socket in the neighbouring segment. Varying the relative dimensions of the ovoid and socket allows for precise control of the movement between each segment. In this design, lateral side-to-side movement is maximized, but rotation and up/down movement is slightly restricted. This more accurately mimics the “tone” and movement patterns of a real snake.

You may get some small adhesions between segments. Simply apply a bit of force to move the joint the first time, and it will be fine after that.

Surface texturing for this design was done with nTopology.
