This is insert for Pax Transhumanity boardgame. I used BoardGame Insert Toolkit by MysteryDough to design it in OpenSCAD. It fits into box with sleeved cards. Small box is for cardboard tokens, the bigger one for wooden cubes and disks. Print on 0.2 layer, no supports needed. For smaller printers like Prusa Mini you will need to split stl with bigger box to 2 parts (box and lid) to fit to print bed.
