Print-In-Place Arca-Style Screw Clamp
This screw-driven quick-release clamp takes dovetail camera plates from about 32 to 48 mm wide, which covers standard Arca-style 38 mm plates. The sliding jaw is printed in place inside V-groove rails, and an M5 x 70 socket cap screw through the fixed jaw pulls it closed onto a captured M5 nut. The clamp is 90 x 62 x 22 mm, with three M5 clearance holes for bolting it to 2020 extrusion, a tripod head or a rig plate, so you don't have to buy a proprietary or discontinued plate.
