SCARA Pen Clamp Lift Slider
This pen carrier is part of the 'NEMA17 Belt-Drive SCARA Drawing Arm' kit. It is a 24 x 24 x 32 mm block that slides in the SG90 tool head's 24.8 mm channel with 0.4 mm of clearance per side. It has a 14.6 mm pen bore and an M3 side clamp that uses a captured M3 nut in a 5.7 mm slot, so it holds pens from 8 to 14 mm. A 16 x 6 mm lug sticks out 7 mm from the +Y face so the servo horn can push it up from below.
