Folding Dice Tray

The original model by Filament Fresser is great, but like a lot of the similar leather designs, once the sides are folded up and pegged in place the base has a tendency to curve upwards at the sides, making more of a bowl shape. Not only does that cause it to wobble and move about annoyingly, but can also affect dice rolling.

All I've done in this case, in fact all I actually needed to do since Filament Fresser had already done all the hard work was thicken the base to make it more rigid. This allows the tray to sit flat when the sides are folded up, and pegged.

This must be printed with TPU, it will not work with PLA, PETG, or any other non flexible material. Since it's going to use most of your print bed make sure it's well levelled and you've dialled in your z offset properly before printing. Don't skimp on the horizontal layers, those are what will give the base it's rigidity.
