608 Dead-Wheel Odometry Swing Arm
A spring-loaded swing arm for a passive odometry "dead wheel". It pivots on an 8 mm rod or M8 bolt and carries two stacked 608 bearings (8 x 22 x 7 mm) in a 16.5 mm hub, so your M8-bolt axle and tracking wheel stay square to the floor. Pivot to axle is 70 mm. There is a 4.5 mm hole for a spring or rubber band that keeps the wheel pressed down, and two M3 heat-set bosses 38 mm apart where you can attach your own encoder bracket. It's a cheap stand-in for commercial odometry pods on skid-steer and holonomic rovers.
NEMA 17 AS5600 Encoder Mount
A closed-loop encoder tower that bolts to the rear face of a NEMA 17 stepper (42.3 mm plate, 31 mm M3 pattern, 24 mm boss clearance) and holds an AS5600 magnetic encoder board 26 mm above the faceplate — right over a 6 mm diametric magnet glued to a standard 24 mm shaft. The deck carries eight 2.9 mm M2.5 holes on 19 mm and 29 mm square patterns so most breakout boards land centred, with a 12 mm sensor window and 12 mm side openings for the cable and a hex key.
