I made some changes to the original model by rounding the corners and including a cutout for the clear plastic lid of the core box. I also included a tray that as an alternative do the dice separator. My thought is that it could be used as a dice tray or a health pool.
I have NOT tested how sleeved cards will fit with the lid.
Printed just fine with .40mm hot end at .20 mm with a 10% infill.
If I have time, I might completely redo this insert so that there are more trays to take out for health and victims. We shall see. But hey, I'm learning CAD! So that's a thing.
The author remixed this model.
