Description
Update: This version introduces a slider box with a snap-in mechanism.
The TetraCube puzzle is a versatile brain teaser. Each of the 8 puzzle pieces consists of 4 cubes.
In addition to the box shape, many other shapes can be built.
The puzzle has a moderate level of difficulty.
The exact settings are not critical — your standard print profile should work fine. The external dimensions of the box are 66 × 66 × 37 mm.
I printed the puzzle with the following settings:
Material: PLA
Layer height: 0.2 mm
Infill: 15%
No supports
No raft, no brim
Lid Fit: If the printed lid jams or is too tight, reprint it with its width reduced by 0.1 mm or 0.2 mm in your slicer.
Snap-In Mechanism: If the lid is too hard to close, file or sand it down slightly using a nail file or sandpaper until it clicks in smoothly. If the snap-in mechanism is not tight enough, you can print the lid 0.1mm or 0.2 mm wider.
