Trapezohedra Magnet Tiles

thingiverse

OpenSCAD trapezohedron tiles with holes for magnets. Trigonal trapezohedron (a cube), tetragonal trapezohedron, and pentagonal trapezohedron. https://en.wikipedia.org/wiki/Trapezohedron Trigonal (cube): Print 2x3 = 6 faces Tetragonal: Print 2x4 = 8 faces Pentagonal: Print 2x5 = 10 faces Use four disc magnets per tile, axially magnetized. Secure them with superglue in the tiles. Check out the User Defined Variables section of the OpenSCAD script for parameters you can change (magnet holes and overall size of tile, total four). Or just use the pre-built STL file (designed for 6mm diameter magnets, 1.5-2mm in depth, leaving a little extra room due to typical 3D printer tolerance issues). Not familiar with OpenSCAD? It's easy to obtain and use! Download it here: http://www.openscad.org. After installation, open the OpenSCAD file for this thing and hit F6 to render (or use menu options up top). File->Export as STL and take it to your slicer! These are also on github: https://github.com/eshira/polyhedra
