Really am enjoying the Modular Tile System, so I stacked a dice tower on top of one of the modules. It can connect to either side and dump dice into either the large or small trays.

Check out a demo here: https://youtu.be/GQeIXmWlTZg

The trays are part of the Modular Tile System I remixed this from, which you can find here: https://www.thingiverse.com/thing:2402641
