Rhombic Triacontahedron Magnetic Tile

thingiverse

OpenSCAD rhombic triacontahedron tile with holes for magnets. https://en.wikipedia.org/wiki/Rhombic_triacontahedron You'll need to print a total of 30 tiles, and 4 disc magnets per tile (axially magnetized). That's 120 magnets in total. I bought mine on eBay in bulk and used superglue to secure them in the tiles. See the User Defined Variables section of the OpenSCAD script for the parameters you may want to change (magnet holes and overall size of tile, total 4 parameters). Or just use the pre-built STL with 6mm diameter magnets. Not familiar with OpenSCAD? It is easy to obtain and use! Download it here: http://www.openscad.org. After installation, open up the OpenSCAD file for this thing and hit F6 to render (or use the menu options up top). File->Export as STL and take it to your slicer! These are also on github: https://github.com/eshira/polyhedra Post-Printing Magnet Orientations Magnet orientation: Parallel sides have the same polarities facing out. Adjacent sides have opposite polarities facing out. For example, make the top and bottom have North facing out, and the left and right have South facing out. Make sure all tiles have identical magnet alignment!!! A good way to keep track is to make your first tile according to the rules above, and use it as a references for every subsequent tile (test your magnets against it).
