Collapsible Side Bag & Town Token Holder for Shadows of Brimstone

I wanted a token tray for a Shadows of Brimstone insert I'm trying to finish up. I only have 40mm of height left to work with so I altered BasHamer's design to make it collapsible. I also removed two of the token shafts, so the trays rest mostly flat at the back. The town location diameter was increased as well, making the tokens easier to remove. The Fusion 360 project file is included with the STLs.

Print the two parts, then place the outer ring over the inner to let them rest on a flat surface, with the inner ring twisted slightly counter-clockwise. To stow it, hold the outer ring with one hand and spin the inner ring clockwise to lock it in place. Unlock it by spinning counter-clockwise again. For game use, lift the inner ring until the lip catches on the outer ring, then spin clockwise to lock it in place.

UPDATE (2017-07-01):

I decided to reduce the excessive number of latches by 3, which works much better now. I only re-printed the outer ring and can twist the rings with just enough force to latch them at the bottom (to stow) or the top (to display), without risk of having them come apart. The STLs and Fusion files have been updated.

Notes:

The overhangs were designed with printable angles that should not require supports.
