Clamp-On Table Cup Holder, Screw Clamp, No Supports

A sturdy cup holder that clamps to any desk or table edge from 10 to 45 mm thick. A printed thumb screw with a swivel pad tightens from underneath, so it won't scratch the table. The ring fits cans, mugs and tumblers up to 92 mm wide, and it has a slot for a mug handle and a flared lip so cups drop in easily. It's five parts that print support-free on a single 270 mm plate, and the ring slides onto the clamp with a dovetail. It comes with STL files plus a ready-to-slice 3MF.
