I really liked the model from Yet Another Dice Tower (https://www.thingiverse.com/thing:3258156), but after printing it I couldn't find a tray to keep the dice from rolling everywhere. Rather than modify one for another tower, I just made this one in Fusion360. It isn't the best or greatest, but it fits the tower and keeps my dice on the table. Figured someone else might like too.
If you make one, I'd love to see it.

I painted it with acrylics to match the tower.
