This is _version 2.0_ of the game, with many exciting upgrades:
- All parts newly redesigned and 50 problems in total!
- The 'bits' have larger hinges that are stronger, easier to print, and fit into the problems more visibly. 
- The bits and problems can no longer be placed upside down by accident. 
- Everything was scaled up 120% so the bits are easy to pick up an manipulate by all hands big and small. 
- The problems have been redesigned to use less material but maintain the necessary rigidity
- I've moved the number labels to the front to make them much more clear. 
- I've rearranged some of the problems so the difficulty increases more progressively at first.
- Thanks to the brilliant solver program by [Darci Peoples](https://darcipeoples.com/), I've changed many of the problems to have fewer solutions, making certain problems significantly more challenging!
- The updated solution guide PDF is attached, including problems 001-050

**_Printing Guidelines_**
- bits : 0.16mm layer height, 2-3 walls, 0.4mm nozzle, 15% infill
- problems : 0.16-0.25mm layer height, 1 wall, 100% infill; *printing the first layer with one wall can help with bed adhesion of the number labels*
- board : 0.16mm layer height, 2-3 walls, 15% infill; *for better grid visibility swap filaments at 1.5mm layer height
- cover : _'wLogo'_ version is two parts. Print combined using a multicolor printer or using [Multipass Multicolor Printing](https://makeanything.design/multipass-multicolor/) technique for single extruders.
- board_premium : filament swap at 8.2mm height for better grid visibility. _'TPUgrip'_ can be glued to the bottom for a nonslip board, printed with TPU 95a or similar flexible filament. Use [E6000](https://amzn.to/3UIOdso) adhesive or similar.
- case : use _'size20'_  together with _'Sleeve_Wide'_ or _'size30'_ with _'Sleeve_Tall'_. Wide sleeve holds 21 or 20 problems with the Handle, Tall sleeve holds 27 or 26 problems with Handle. Handle can be used loose (slide in from the bottom of the sleeve) or glued into place.

Due to the success of my Mounted Trash Bin, I've created this standalone version. It's a large trashcan that prints in several parts optimized for 3D printing, with plenty of variations and optional additions for total customization!

---

_**Printing & Assembly**_

Due to the optimized design, you can print most of these parts using default print settings. Nearly all the parts print without supports, but the new Locking Inner Rim requires support generation for a long bridge to allow for the improved lid flap.

Here is a description of the various parts:

- **Lid_Locking** : The lid of the trashcan, which snaps into place when fully opened for one handed operation. Print with 4 shells/perimeters for a hinge longevity.
- **Top_Rim_Inner_Locking** : Snap the Lid into this part. _Enable Supports!_
- **Top_Rim_Inner_Locking_Loose** _(optional)_ : A looser version of the Inner Rim, useful for thicker trashbags or less precise printing. _Enable Supports!_
- **Top_Rim_Outer** : This is the part you wrap the top of your trash bag around, which is then sandwiched into place with the Inner Rim. _There is an oval notch on the front of both the Inner and Outer Rim. Make sure they're oriented the same way!_
- **Lid_OG** _(optional)_ : The original version of the lid, without a flap on the front, and doesn't lock in the open position
- **Top_Rim_Inner_OG** _(optional)_ : Only use with Lid_OG
- **Corner_Post** : The four vertical posts that connect the Top and Bottom Rims. I would suggest 4+ perimeters/shells for strength. Print 4. Align with the channels on the Bottom_Rim and snap all 4 into place. Then set the Top_Rim_Outer onto the four posts and press each corner straight down to snap into place.
- **Bottom_Tray** _(optional)_ : This tray rests inside the Bottom_Rim to support the bottom of the trash bag. Useful if you're throwing away heavy things that might rip the bag if unsupported.
- **Bottom_Tray_Deep** _(optional)_ : Another version of the bottom tray with higher walls. Usefull if you are tossing things that might leak.
- **Foot_TPU** _(optional)_ : Small feet to be printed with TPU or another flexible filament. These are simply glued to the corners of the bottom of the Outer_Rim to add a cushion between bin and floor, for protection and non-slip.
- **Walls_Plain** _(optional)_ : Conceal the trash bag and keep it from bulging out if it's larger than the bin. Print in vase mode with 0.6mm extrusion width and 0 top/bottom solid layers. 
- **Walls_Fluted** _(optional) : Same as Walls_Plain but with a fluted texture that adds a bit of strength and decorative appearance. More likely to warp from filament shrinkage while printing!

Yes, it's a lot of parts, but the result is a nice, large, super functional trashcan that you can customize to your needs! Leave a comment if you have any questions or requests and I'll respond ASAP!

- **Nov 2, 2025 Update** : Added an 'ExtraFlex' version of the Corner Posts, which makes it easier to take apart and put together over and over.

This is what I call a Filament Straightening Block. I designed it to straighten sections of filament to insert into 3D prints to act as axles or hinges.  I could instead design axles or hinges into prints but sometimes I want them thin AND strong. Using unprinted filament would provide both of those qualities...I just needed it to be straight.  Specifically, I used these for my recent project the Mini Magnetic Tile Haunted House Collection but plan to use it in other projects in the future also.

****3D Print Settings****
PETG preferred because of it's high heat tolerance (but PLA will work too:)
0.2mm Layer Height
20% Infill
No supports needed

Note: You will need two rubber bands to secure the two halves of the block together.  (I did design collars to the halves together which you could also use but I like prefer the rubber bands.)

To use this block, secure the two halves together with a couple rubber bands (or collar pieces).  Next heat a pot of water over the stove to around 160F (~70C) and carefully insert sections of filament into the hot water (please be careful not to burn yourself). Swirl the filament around until it gets soft (like a cooked noodle) and then insert it into one of the holes in the block, threading it all the way through.  Repeat (there are five holes) until filled.

Let the filament sit and set for a half an hour and then when you open it the sections will be straight:)

See the attached video to watch how I did it.

Have fun printing!

SKEWBITS v2.0 Puzzle Game // Full Set w. Problems 001-050

I made these mounted trash bag bins specifically for the Red/Green waste bags used in my region of Sweden, but you may find them useful for your own situations as well! I have mine mounted on the cabinet drawer under my kitchen sink for super convenient and accessible composting.

The design consists of four parts:
- A lid
- An inner rim that connects to the lid
- An outer rim that holds the trash bag and snaps onto the wall mount
- A beefy wall mount that securely clips onto the rim.

Default print settings should work out. I used PC filament to make the mount extremely resiliant but I suspect most filaments should be sufficient. The rest of my parts were printed with PLA. Share your results if you try something else!

The mount has holes for up to 6 wood screws, but I only used the top 4 and it's enough, even with short 19mm screws. The holes are sized for threads up to 4mm wide, but you should be able to expand the holes by pre-drilling if necessary.

**_July 18, 2025 Updates_**
- The lid and inner rim used to be a single print in place part, but this has proven to be unecessary. The parts are now split and you can flex the inner rim to snap the lid onto the hinge.
- Added a new **locking** lid! This upgraded lid snaps into the open position to stay up on its own.
- Looser version of the locking lid is also included. Useful for thicker trashbags or less precise printers.
- **note:** You **must** use the Locking Inner Rim together with the Locking Lid.
- **note:** The new Locking Inner rim requires **support material** generation turned on! It's a small amount of supports, but this enables the flap on the lid for easier handling.
