Pentagonal Hexecontahedron Magnetic Tile

thingiverse

Human: I built an OpenSCAD model for a pentagonal hexecontahedron tile with holes for magnets. Instructions This is a single tile for a pentagonal hexecontahedron. You can read more about it here - http://en.wikipedia.org/wiki/Pentagonal_hexecontahedron You will need a total of 60 tiles and four disc magnets per tile that are axially magnetized. That's 240 magnets in all. I bought mine from eBay in bulk and used gel-type superglue to secure them in the tiles. Magnet orientation: The two longer sides with magnets must have opposite polarities facing out. The two shorter sides with magnets must have opposite polarities facing out. The remaining shorter side has no magnet hole. To make all the tiles identical, create your first tile according to these rules and use it as a reference for each subsequent one. Make sure to test your magnets against this original tile to keep everything in order. If you need to change anything about the magnets or the overall size of the tile, see the User Defined Variables section. It has four parameters that you can modify - magnet hole dimensions and total size. I printed my tiles with ReplicatorG using the default acceleration settings and without any raft or support material. They took approximately 20 minutes to print each one. Some people choose to decorate their tiles with gold liquid leaf paint, while others keep theirs plain in black ABS plastic. For my own project, I used a mix of both approaches - twenty tiles got painted with liquid gold and the remaining forty were left unpainted in black. To give you an idea of the dimensions I worked with, the longer side measures 4 cm long, and the thickness of each tile is set to 1 cm.
