2020 Swivel Pi 4 Panel Mount
This print-in-place swivel mount clamps to the side of a 2020 extrusion with two M5 T-nuts. It carries a 71 x 70 mm board plate that swings about 120° on a captive 8 mm pin, and an M3 screw pressing on the pin locks the angle. The plate has the Raspberry Pi 4 hole pattern (58 x 49 mm, 2.9 mm holes for M2.5 standoffs), so you can angle a Pi, display or driver board on a robot frame without designing a new bracket.
