Scotch-Yoke Wing Slider
This slider is part of the 'SG90 Scotch-Yoke Flapping Wing Rig' kit. It is a 56 x 26 x 10 mm block with a 40 x 13.5 mm round-ended through-slot. The crank's 624 bearing (4 x 13 x 5 mm) rolls in the slot and turns servo rotation into a ±13.5 mm vertical stroke. A 32 mm wide top tab holds two M3 heat-set inserts (4.0 mm bores, 8 mm deep) 20 mm apart, where the wing drive links bolt on. The 4 mm edge bands on both sides are left flat to slide between the frame pads and the retainer strips.
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.
624 Bearing Appliance Slider Rail
A 150 x 30 x 18.5 mm roller rail that lets a heavy stand mixer, espresso machine or air fryer be pulled out from under the upper cabinets with one hand instead of being dragged across the counter. Each rail carries two 624 bearings (4 x 13 x 5 mm) on M4 x 25 screws — 4.5 mm clearance hole with a recessed head on one side, 3.4 mm self-tapping thread on the other — so the outer races sit 1.5 mm proud of the rail and roll; the 22 mm wide top tray with a 2.5 mm rim keeps the appliance foot from walking off. Print two rails per appliance.
