Hexaflexagon REDO v5

thingiverse

UPDATE: Now available on my Etsy! http://www.etsy.com/shop/3DJoe3D I've added sliced versions for easier two-color printing - details below. This addictive math toy is a favorite among everyone who prints it! It's by far the most fun printed-in-place-hinges toy I've encountered. After all my attempts to print whpthomas' model failed, I decided to make my own Trihexaflexagon. The problem was that it wouldn't open without breaking and flex without effort. I use an Ultimaker2 and even customized the tolerance up to 0.55, but nothing worked for me. To fix this issue, I made indented links looser and now they print better for me. The indented clasp works much better for me now with no heating problems. I added chamfers for squished first layers. I kept it thin, at only 3.5mm high. It's 190mm long (35mm per triangle side). I've also added a version with 1, 2 and 3 dots. Now there's even a version with patterns! And, as requested, I included a blank version. I hope this helps! If you make one, please share your pics! The original model remains excellent work. I've also uploaded it to Shapeways in case you want one printed for you! The slices for two-color prints were made because I prefer not to risk changing colors mid-print. This way it's three prints stacked on top of each other - color 1, color 2, and color 1 again. They have a 0.3mm frame around them to center them exactly in the same spot on the plate. To keep slabs b and c floating at the right height, I included this extra feature. My slicer ignores the frame because my nozzle is 0.4mm, but if your slicer includes it for the b and c slabs, the head will probably crash into already printed layers. Be sure to check your print path carefully!
