Drive around the mÃ¶bius strip!
The earring loop will not move freely, but only drive arround the mÃ¶bius strip- so there is only one position where it is straight enough to wear.
You need a 3D printer to print these digital, virtual designs of actual objects.
See screenshot for UP snobs. Check "print unsolid model".
Printing it at 2x scale will result in a better mÃ¶bius strip, the tolerances are still tight enough.
I am tired of uploading every single file, so zip it.
Update: Chain version does not print well with settings above, the rings get to fragile. Try running them through netfabb/meshlabb to fix them to avoid some issues.
