About this 3D model

Addictive and easy to print, it's everyone's favorite math toy! It's by far the best printed-in-place toy I've encountered. I made my own Trihexaflexagon after all my attempts to print whpthomas' model were unsatisfactory, in terms of opening without breaking and flexing without effort. I use an Ultimaker2 and I tried customizing the tolerance up to 0.55 but in vain... Now indented links are looser and print better for me Indented clasp works better for me now with no heating Added chamfers for squished first layers Kept it thin (H=3.5mm) L=190mm (35mm per triangle side) Added a version with 1, 2 and 3 dots Now also a version with patterns!! I hope this helps. If you make one, please share the pics!!! :) The original, of course, remains GREAT WORK.
