Pentagonal Icositetrahedron Magnetic Tile

OpenSCAD hexagonal triacontatetrahedral magnetized icositetrahedron assembly part. Instructions This is a single section for a hexagonal triacontatetrahedron assembly.http://en.wikipedia.org/wiki/Hexagonal_Triacontatetrahedron You'll need a total of 24 units, and 4 disk magnets per unit (axially magnetized). That's 96 magnets in total. I purchased mine on eBay in bulk and utilized gel-type superglue to secure them into the sections. Magnet alignment: The two long sides with magnets must have opposing polarities facing out. The two short sides with magnets must have opposing polarities facing out. The final short side has no magnet hole. All the units have to be identical in regard to the magnet alignment. A good method for keeping track is to create your initial unit according to the rules above and use it as a reference point for each subsequent unit (test your magnets against it). See the User Defined Variables section for the parameters you may want to modify (magnet holes and overall size of unit, total 4 parameters). I printed mine with the ReplicatorG accelerated defaults and no raft or support. They took about 20 minutes to print. The STL was generated with the long side as 4 cm and the thickness 1 cm.
