There are four token trays here, each with a different configuration and a snap-on lid. I printed one of each to store all the tokens from my massive Shadows of Brimstone boardgame collection, but of course they could have other uses.
Each tray measures 227mm x 141mm x 33mm (with lid on).
Two of these fit side-by-side in less than half of a Shadows of Brimstone core box. The inside dimensions of those core boxes is 465mm x 283mm x 98mm, so four token trays take up one end of a core box with room for manuals on top. I attach a piece of duct tape to each box so I can easily lift them out (seen in the photos below).
Prints without support, designed for 0.4mm nozzle and 200um layer height. The lids snap-on and hold very nicely for me.
