This token box/tray is meant for the Arkham Horror Living Card Game tokens that are used during the game. I didn't include any room for the Chaos tokens that aren't in the Chaos Bag. I've included a blank lid in case you don't like the design of the Elder sign.
The magnets are measured to be 6mm x 3mm. The holes in the model are 6.1mm diameter, I find this to be a good fit. I don't need to scrape away any material to fit the magnets in, but there is no need for adhesives either. Depending on your printer's tolerances, you may have to force it a little, or use adhesive, but this works great for me.
I also made the holes on top 3.2mm deep, but for holes on the bottom of the lid and top tray I made them 3.3mm deep (to compensate for the slight droop from the bridge. This is so the magnets can fit flush with the surface.
