This is a small combination dice organizer and dice rolling tray. I wanted to make a piece that would store and organize my dice and double as a rolling tray.

The spaces are intended to allow larger d20s (~24mm side to side) in each, but not chonky d20s. All other dice are smaller and will fit just as well. The 7 spaces on either side are for each set and include raised numbers in the space. The d6, d8, d10, and % are raised higher to reduce rattle. The center 3 spaces are for additional dice you may want to include.

There are spaces on the left and right to allow 3mm deep x 10mm diameter magnets. These magnets should ensure the lid does not fall off. The lid is intended to have felt or a similar fabric glued to it to quiet rolling in the tray. There is not clearance for felt on the sides of the tray/lid.

This model was created with FreeCAD. Original model file has been included.

Update 01; Reduced clearance from sidewalls (0.5mm to 0.25mm). Added more, larger magnets to sides.

Update 02; Increased clearance from sidewalls (0.25mm to 0.35mm). Chamfered organizer edges to allow for the top tray to be more easily closed.
