TetraPentaTan Puzzle

thingiverse

Polytans consist of right-angled isosceles triangles joined together. There are 6 tetratans (= 4 tans) and 8 pentatans (= 5 tans) that fit into the tan lattice. The puzzle consists of 14 puzzle pieces and a slider box. There are 133 solutions and it is not easy to solve. In addition to the square, the puzzle can be used to lay many other shapes. The puzzle pieces are used on both sides. The size of the sliding top is crucial. If it's too narrow, the bumps on the top won't snap into place. If it's too wide, the top can usually still be inserted, but it becomes difficult to open. If the top doesn't fit, it is advisable to adjust its dimensions in the slicer and reprint it. Recommended adjustments are only small increments ranging between approximately 0.2mm and 0.3mm in width (only in width). Here is a short video explaining this: https://youtu.be/vve-SCg9ln8 I printed the puzzle with the following settings: Material: PLA Resolution: 0.2mm Infill: 20% no supports no raft, no brim A YouTube Video about the Puzzle: https://www.youtube.com/watch?v=WsPSvNP0r20 More information about puzzles whose pieces consist of simple geometric shapes (polyforms) can be found at http://www.pentoma.de (in german)
