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.
