Rocker Arm With 608 Pivot
This is the main suspension rocker for the 'NEMA17 Rocker-Bogie Mars Rover Chassis' kit (print ×2). Both faces are identical, so the same print works on the left and right sides. It is an 8 mm thick flat arm about 154 × 104 mm. The main pivot is a 22.05 mm through-bore that takes a press-fit 608 bearing on an M8x40 bolt. The front NEMA17 pad has four 3.4 mm M3 holes on a 31 mm square and a 22.5 mm pilot hole. The bogie pivot boss has an 8.4 mm hole for the M8x35 bolt, and the differential ear has a 3.4 mm hole for an M3x25 link bolt.
