8 inch DnD Dice Tray/ Storage Container. it has 8 removable storage bins that clip on to the outside of the dice tray while playing and are held inside the dice tray while in storage or travelling. I used some velvet with adhesive backing to put inside the dice tray which measures about 1mm thick and it still allows the lid to close easily. The tray itself has 16-8mm by 2mm magnets and the lid uses 8-8mm by 2mm magnets. I used superglue to hold the magnets in place. for the tray base I use Normal auto supports, for the lid I don't use any supports and print face down. and for the storage cups I use tree auto organic supports. I included 1 blank storage tray and 7 storage trays marked %, D20, D12, D10, D8, D6, D4.
