Round Dice Castle with Removable Tray

I took the original design and made the exit tray removable so the print would fit on my Monoprice Mini Delta. When I tested this, the tabs on the tray were too big for the slots on the castle, so I had to shave them down. I have since edited the design to reduce the size of the tabs, so they should be a better fit now, but I haven't printed it out to check yet.
