Summary

I printed the Tiny Dice Tower (no supports needed) by cokane but I found the the dice tended to bounce out of the top since it was optimized for shorter printers. I used TinkerCad to add a funnel to the top to control the dice. Works much better and still needs no supports.
Size: 112mm high by 126mm by 78mm.

Post-Printing

Used Testor's model cement in the RED tube to glue the ramps in. The blue tube glue and the liquid glue will not work on PLA but the Testor's model cement in the RED tube works very well.
