Pen Lift Clamp Slider
This slider is part of the 'NEMA17 Cantilever Pen Plotter' kit. The 34 x 18 x 16 mm block runs on two 4 mm steel guide pins, 24 mm apart, through 4.4 mm slip bores. It holds any 7–12 mm pen in a 12.5 mm bore, clamped by an M3x12 screw and a captured M3 hex nut. An SG90 servo horn pushes up on the 12 x 14 x 5 mm lift tab to raise the pen. The two guide pins stop the wobble and drag you get when the lifter hangs from the servo alone.
