Insert to hold the hex pieces in Fish Cook by Cheapass Games. It should just barely fit in the box on top of the boards and rules. It's also sized so that it lines up with the market and is easy to grab pieces from.
My initial version was a bit of a tight fit so I bumped up the hex radius from 12mm to 13mm.
Made with OpenSCAD and script included here. If you click on customizer, there are 4 variables to configure it:
- slots: the number of hex slots
- disks_per_slot: how many hexagonal pieces should fit in a slot
- disk_radius: the radius of the hexagon pieces (in millimeters)
- disk_height: the height of the hexagon pieces (in millimeters)
