Tray for mini poker chips

See https://boardgamegeek.com/thread/2951180/ceramic-mini-chips-status-fulfilling-pre-or

This fits 40 chips per column, 7 columns per tray. Second layer can stack on top of first layer, or subsequent second layers. Lid should fit either a first or second layer.

All layers and lid have a spot for 2mm by 1mm disk magnets to help the case latch.

For printing - some supports needed for underside of the second layer. Minor supports needed for handles of the lid.

Warning: I printed an earlier variant of the files and have made changes since, resulting in what I posted here (mostly to lift the 2nd layer off the chips a bit and add fillets). The lid is being printed now. So the exact files here are untested - print at the risk of losing plastic - if anyone has a successful print please let me know and I'll remove this warning. It should work fine :)
