Schoens I-WP Egg

This egg design is part of a series of “10 Decorative Minimal Surface Eggs”. The series was originally created in 2021.
See my page for a more recent similar series of hollow “10 Easter Eggshells” that can be used to store objects or candy.
The descriptions below offer specific suggestions for printing. One general word of caution is when using “tree” supports, be sure to add “support blocks” to prevent the tree structures from extending up into the interior of the egg. They’ll be impossible to remove.
Expect to do a bit of post-print cleaning with each piece.
Schwarz' P Egg
This relatively simple egg requires a small amount of tree support to the bottom bulge. This is a good one to start with.
Schwarz’ D Egg
The Schwarz D Egg has some overhangs that may not be properly supported by standard supports. The piece is provided plain and with custom supports.
Schoen’s Gyroid Egg
The Schoen’s Gyroid Egg requires tree supports for the bottom third or so.
Schoen's Batwing Egg
The Schoen's Batwing Egg is tricky in that it has some rather large horizontal surfaces. The model shown was printed with an extensive amount of tree support. While the overall structure held up, the undersides of the horizontal surface required a lot of cleanup.
Fischer-Koch S Egg
The Fischer-Koch S Egg has some overhangs that may not be properly supported by standard supports. The piece is provided plain and with custom supports.
Schwarz’ CLP Egg
This relatively simple egg requires a small amount of tree support to the bottom bulge. This is a good one to start with.
Schoen’s I-WP Egg
Schoen’s I-WP Egg requires tree supports for the bottom third or so.
Schoen’s F-RD Egg
Schoen’s F-RD Egg has some overhangs that may not be properly supported by standard supports. The piece is provided plain and with custom supports.
Schoen’s F-RD(r) Egg
Schoen’s F-RD(r) Egg requires tree supports for the bottom third or so.
Fischer-Koch C(Y) Egg
Fischer-Koch C(Y) Egg has some overhangs that may not be properly supported by standard supports. The piece is provided plain and with custom supports.

Brain Breaker Blocks

If you’re bored of Lego, this 3D printed self-interlocking construction block will break your brain. It takes minutes to print, months to figure out!

See here for video for demonstrates of the concepts outlined below: https://youtu.be/j10wzy0qGOg 

Officially known as an “SL Block,” this octocube shape is part of a family of “topologically interlocking assemblies,” that is, shapes that hold together without the use of connectors or adhesives to form self-interlocking structures. Self-interlocking structures have interesting architectural and engineering applications.

A ends of a single “SL” block resemble an “S” and an “L.”. In assembly, SL blocks always occur in pairs, called a “Conjugate Pair.” In the pictures and video, conjugate pairs are shown with one white and one black piece.

Conjugate pairs lock together in six different ways, called “engagements,” to form “SL Strands.” Each type of engagement adds a unique translation or rotation to the SL Strand. The six types of engagements are denoted as “h,” “t,” “s,” “d,” “a” and “y.”

Using this system, the SL strands can be represented as strings consisting of six letters that stand for
the six types of engagements.


The first example in the video is an “h4” SL Strand. “h” engagements are straight with no rotations or translations, so the strand is straight.

The next example is an “a4” SL Strand. “a” engagements create a 90 degree rotation but no translations, so the “a4” strand makes a closed, cube-shaped structure.

The final examples in the videos show more complicated “(as2)4” and “(dth)4” strands. These modules can then be connected to form larger and increasingly complex self-interlocking structures.

600-Cell Central Rings.stl

This is a three-dimensional shadow of selected cells of the four-dimensional shape called the “600-cell.”

See here for video: https://youtu.be/IhW48X29e0g 

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.

This model is designed for resin printing.


Truncated Cube Tealight Holder

This design is part of a set of Tealight Holders derived from mathematical surfaces and lattices. 

The Tealights will print without supports, but you may want to ensure your machine is well calibrated for bridging and that you are getting good layer adhesion.
