Collapsible Dice Tower

A friend of mine asked me to tackle the idea of making a dice tower that collapsed down and fit in a box. After a few weeks for printing and testing I finally finished my design. I designed the openings to always be about 30mm between flaps and the final opening at the bottom. This allowed my MTG life counter dice (the biggest dice I own) to fall through without any issues.

The tower is made up of 4 walls, 3 of the flaps, and 6 flap supports. The "p3" and "p4" walls stand for 0.3 and 0.4 mm c
