Hexaflexagon REDO v5

UPDATE: Added sliced versions for easier two-color printing, see details below.

Addictive and easy to print, it's everyone's favorite math toy!

It's by far the most fun printed-in-place-hinges 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!!
• Now also a blank version, as per request.

I hope this helps. If you make one, please share the pics!!! :)

The original, of course, remains GREAT WORK.

Also I've put this up on Shapeways, in case you want one printed for you!!

The slices for two-color prints were made because I don't like to risk changing colors mid-print. This way it's 3 prints one on top of the other, color 1, color 2, color 1. They each have a 0.3mm frame around them to center them exactly in the same spot on the plate, and to keep slabs b and c floating at the right height. My slicer ignores the frame because the nozzle is 0.4mm, but if your slicer includes the frame for the b and c slabs, the head will probably crash into the already printed layers, so check the print path carefully. (and maybe work around this somehow if that's the case)
