Twisted Torus Unit
by phooky, published
This is George Hart's reconstruction of a 16th-c. wooden puzzle, currently in the Schloss Ambras Museum. Print out 76 units and reconstruct the original! A full description is available at http://www.georgehart.com/rp/torzle/torzle.html.
I've scaled the basic unit to be a reasonable size in millimeters. You may want to go somewhat smaller to reduce print times.
The other files diagram how to assemble the entire piece.
