Dice tower with catch tray
A dice tower randomises rolls and keeps dice from flying off the table, which matters when a game night involves drinks and miniatures. A solid design stands roughly 150 to 180 mm tall with three staggered internal baffles angled at 30 to 45 degrees, a drop chute at least 30 mm wide so oversized d20s never jam, and a catch tray with a 6 mm lip. Walls of 2 mm print fine in PLA, and a chamfer on the tray edge helps dice settle.
With SpeakCAD you describe the tower you actually want, matched to your dice size and the space on your shelf, then tweak the baffle angle or tray depth in the chat until the preview looks right. Trying it in the browser is free, and the STL only costs credits when you download.
Design a dice tower 60 mm wide, 60 mm deep, 170 mm tall with three internal ramps at 40 degrees, a 35 mm square opening on top, and an attached catch tray 110 x 70 mm with 8 mm walls and 2 mm wall thickness overall.
