Summary

This Thing takes Edward Nelson's 1897 six piece Chuck Puzzle and applies a rotational twist to each pair of pieces turning what is a fairly simple puzzle into a more complicated one.

Where all three pairs of Puzzle pieces are rotated through 5 degrees the result is Stewart Coffin's Grizzly Burr puzzle.

Instructions

EIther download the OpenScad file, adjust the parameters to generate your own unique Chuck Twist puzzle. If you tweak the design it is possible to generate a puzzle that can neither be put together or taken apart so it is well worth rendering the assembled version to check the key piece is appropriately positioned/shaped You may need to play with tolerances a little current settings work for me when printing in PLA.

Alternatively download one of the pre-generated STL files (four puzzles in one thing!) :

  • Chuck Twist 14-14-14, all 3 pairs rotated through 14 degrees
  • Chuck Twist 14-10-6, 1st pair rotated by 14 degrees, 2nd by 10 and 3rd by 6
  • Grizzly Burr, all three pairs rotated through 5 degrees
  • Chuck Twist 0 - no rotations applied, the simple original puzzle.

The ChuckTwist assembled STL file is just to show the final pieces in assembled position it is not intended for printing....

Enjoy

Does anyone have a solution? My office mates and I have been toiling over this for 2 weeks. Please help us if you can.
