I wanted to make a Dice Tower of my own design, and this is it. I designed it to print with no supports or raft by letting the dice tray to hold it all down without wasting filament on raft or brim. The windows and doors have been arched, and the dice ramps are steeply angled to negate the need for wasteful supports. I've included some seriously messed up OpenSCAD code, in case you want to take a look.
