Plastic Game (Poker, Roulette, Craps, etc.) chip storage
I'd bought a 10-color poker chip kit from Amazon for use with an old roulette game, and I needed a way to store the 1" (25.4mm) plastic gaming chips. This is designed to store ~100 chips per slot. There are spacers to take up space when the chips are inevitably lost. You shouldn't need the spacers until there's about 15-20mm of space above the chips (which would make them loose enough to tilt and slip out).
SKP files attached, too to make adjustments easier. For different diameter chips, you should just be able to get away with scaling up or down the design. If you need to store more/less chips, take care to add to/take out the center of the chip holder "tower" so you don't mess up the clips for the top. It also shouldn't be too difficult to adjust for fewer chip colors.
I used PLA for this, and the top is designed so not much flex is needed to make the wings move over the locking nubs on the sides of the chip holder itself. I don't get the sense that it will break.
