articulated support arm

Articulated support arm: use one clamp to attach to the desk, the mirrored clamp to hold a webcam or a light or something else

All parts can be printed at 0.3 mm layer height and at the maximum speed your printer can do reliably, which for me is 60mm/s for PLA and 35mm/s for PETG. The screw threads are designed to be forgiving as long as you print the screws vertically with an optional brim. The clamps can be printed laying flat. No parts require supports.

The camera mount is not threaded, depending on how lax your printer is you might be able to force the screw in or, as in my case, heat the screw first time or use a 6mm drill to adjust the hole. Once adjusted with the drill the standard tripod screws go in easily and stay firm.
