Tray System for Massive Darkness figurines (25 mm base)

I made a system for storing Zombicide figures of all in one standard box. This is my next work - system for storing Massive Darkness figures of all in one pledge box (Lighbringer pack). Now the height of the structure is 10 cm, ie there are fits 4 figures. Which is very convenient, because in this game often 16, 12, 8 and 2 identical figures.

Each wall of this frame assembled from 2 same Wall details. You need 6 copies of the Wall. It connects by 3 pieces of Joint. Between each other, the walls are also connected transversely by Stiffener (6 pcs) for rigidity. I added complete sets of walls for one-time printing.

Work in progress. Other files will be added when I tested it.
I need to make TrayBackstop and solid parts. Also I plan to make new trays for monsters with more wide bases.

The dimensions of the final construction are 298 mm x 298 mm. Height is 102 mm.
