This model is a dice tray inspired from leather dice trays I noticed while playing DnD.

I used Colorfab Varioshore TPU, in order to print living hinges and have an abrasive resistent material. 

Does not work with rigid materials, no PLA/PETG/etc !!!

Its a long print, make sure your extruder can handle flexible materials before manufacturing.

Check bed level as well, as it uses 200x200 mm of the buildplate.

Chamfers have been modeled, the picture is the first protoype without them. It will fold even better with the chamfers.

Any feedback is greatly appreciated.
