Pentagonal Icositetrahedron Magnetic Tile

thingiverse

OpenSCAD pentagonal icositetrahedron tile with holes for magnets. Instructions This is a single tile for a pentagonal icositetrahedron.http://en.wikipedia.org/wiki/Pentagonal_icositetrahedron You'll need a total of 24 tiles, and 4 disc magnets per tile (axially magnetized). That's 96 magnets in total. I bought mine on eBay in bulk and used gel-type superglue to secure them in the tiles. Magnet orientation: The two long sides with magnets must have opposite polarities facing out. The two short sides with magnets must have opposite polarities facing out. The last short side has no magnet hole. All the tiles have to be identical with regard to the 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). See the User Defined Variables section for the parameters you may want to change (magnet holes and overall size of tile, total 4 parameters). I printed mine with the ReplicatorG accelerated defaults and no raft or support. They printed in about 20 minutes each. The STL was generated with the long side as 4 cm and the tile thickness 1 cm.
