The file 'George Hart’s 3D Sculptures For Makerbot/RepRap-class 3D Printers 3D Printer Model' is (stl) file type, size is 1.1MB.
George Hart has a lot of great models over at his MakerBot page: http://www.georgehart.com/rp/makerbot/makerbot.html
He's given me his blessing to post these to Thingiverse where they can get some additional exposure!
This subgroup of parts is the printable math structures-- I'll be posting the more puzzle-like ones in a separate post. He reports these can require a lot of cleaning, but otherwise come out pretty nicely!
