Cadded up this dice tower to get something that was a bit more generic than the medieval looking ones already out there, but still with a tray for the dice to land into.

Printing:

Printed with a raft at 200degC using PLA and supports only under dice exit arch.
Layer height of 0.18mm
Dice tower is pretty damn large at 100% - 140 x 120 x 120, would be best for oversized dice
Printed at 75% is perfect for smaller printers and regular size dice - 105 x 90 x 90

Lid is a loose fit on top of the dice tower, I haven't tried yet, but try scaling down for tighter tolerancing.

Included the Solid Assembly so feel free to remix
