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 clearance between the support walls and the T shapes that make up the walls with the flaps on them. While The 0.3mm fits a bit more snug I wanted to be sure people could print the tower and use it without much in the way of sanding or wearing the parts down. the little support pieces for the flaps only have a .1mm clearance so I use a pair of pliers to force them into the home. This works fine for regular dice, but if you use metal dice I recommend adding a tiny bit of glue to make sure it sticks
