Presenting the mechanical trap door dice tower. A simple turn of the tower's parapet simultaneously raises the swinging doors and releases the dice into the tower.
At the same time, the tower door opens, allowing the dice to escape and revealing the dice roll.

The mechanism was tested with a standard sized DnD dice set (all 7 dice can be rolled at once)

Assembly:
The assembly is great fun. Every part has its own kind of clicking mechanism, which makes assembling a brease. A large part of the mechanism is print-in-place, meaning it comes fully assembled and functional from the print plate. No extra tools or glue are needed because everything is printed.

Minimum printbed size:

~420g of PLA

UPDATES:
