I made a dice box for Dungeon Masters in mind. The dice box cover folds out and can be use as a DM screen. It can either be set onto the table top or slid into the back side grooves of the dice box itself.
I also made a dice box mat to dampen the noise if printed with TPU or NinjaFlex like materials.
You will need 4 M3 x 30mm socket head cap screws (SHCS) to use as the hinge pins for the screen folds. M3 x 20mm would also work but I wouldn't go any shorter than that. The bolts should spin freely through the main cover hinge holes while tight enough to self tap the screen hinge holes . Be careful not to over tighten.
Note: When printing the screen sections, you will have to mirror the STL file in order to get both LH and RH screen folds. The STL file included will print the RH version.
