Puzzle Knot
thingiverse
A sculpture of a math knot puzzle. Not a puzzle you take apart or put back together - just a visual puzzle. Instructions This sculpture was designed in Modo. It requires support if you print on extrusion printers. I printed at the largest size on my Replicator 2 and it took quite a while to remove all the support structures - see the photo of the raw print before removing support structures (supposedly it is now easier with software upgrade but I would like to try it again). I have included it in stl and thing format for MakerWare.
