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.

We closed the loop by cheating. One link is not like the others. :)

Please tell us how you closed the loop.

I ended up filing the slot slightly larger on one link and filing one wedge part down just a bit from top and bottom

I have 25 of the 76 printed, doing them in 25 part batches, last batch will be 30. I dont see how the loop will close without modification, or without heating the last one up...

Any hints?

I saw this on boingbong and immediately thought it should be on thingiverse. Well done.

probably a good part for a conveyor belt platform. Would it print on it's side so I could squeeze a few on one platform?

(Also, see http://www.thingiverse.com/thing:3475http://www.thingiverse.com/thi... for another of George's constructions)

Cool! Photo of one printed and assembled?

I have printed out George's twenty piece puzzle and tried to get the puzzle-heads at my work to put it together, but so far they haven't got anywhere!
