Winch Fairlead Top Brace
This top brace is part of the 'N20 Self-Locking Worm-Drive Winch' kit. It is a 96 x 50 x 6 mm ribbed plate that bolts across the tops of both 608 bearing cheeks with four M3x12 socket head cap screws, which go into the cheeks' M3 heat-set inserts through 3.4 mm holes with 6.5 mm counterbores. It holds the cheeks square and guides the line through a 32 x 10 mm round-ended hawse slot. The slot has 1.5 mm 45° chamfers top and bottom so the line never rubs on a sharp edge.
N20 Worm Motor Sled
This motor sled is part of the 'N20 Self-Locking Worm-Drive Winch' kit. It holds an N20 gearmotor (12 x 10 mm gearbox, 3 mm D-shaft, fixed with two zip-ties) and a 624 tail bearing (4 x 13 x 5 mm, 13.05 mm press pocket) in line with the worm axis. It bolts to the base plate with three M3 heat-set inserts (4.0 mm bores) and M3x10 screws, and measures 22 x 95 x 24.5 mm. The middle insert bore goes through the floor because the floor under the worm is only 6 mm thick.
608 Axle Bearing Cheek
This is the upright bearing cheek for the 'N20 Self-Locking Worm-Drive Winch' kit. Print two. Each cheek is a 9 x 50 x 70 mm plate. It takes a 608 bearing (8 x 22 x 7 mm) in a 22.05 mm press-fit pocket that is 7.1 mm deep and has a 0.5 mm lead-in chamfer. A 12 mm through-hole lets the 8 mm steel axle pass, and four M3 heat-set inserts (4.0 mm x 8 mm bores) fix it to the base plate below and the fairlead brace above.
Worm Winch Base Plate
This is the base plate for the 'N20 Self-Locking Worm-Drive Winch' kit. It measures 146 x 105 x 6 mm and sets the position of every other part: the two 608 bearing cheeks and the N20 worm motor sled each bolt on with M3x10 socket head cap screws, inserted from underneath through 3.4 mm holes with 6.5 mm counterbores, into M3 heat-set inserts. Four more 3.4 mm corner holes mount the winch to your robot. Five rounded windows remove weight, and raised corner marks show where each cheek sits.
5 mm Shaft Capstan Winch Drum
A flanged capstan drum that bolts straight onto a 5 mm stepper or gearmotor shaft (5.3 mm slip-fit bore) and pulls cord — motorising a roller blind or curtain, or driving a cable-tendon robot joint. 37 mm drum core, 48 mm flanges, 54 mm tall, with two M3 heat-set inserts at 90° for grub screws and two 3.6 mm cord anchor holes that let the knot hide inside the ribbed hub cavity.
