Inchworm Servo Pedestal Chassis
This is the rear body of the 'SG90 Sawtooth-Foot Inchworm Crawler' kit. It is a 136 x 60 x 4 mm deck with a grid of 3.4 mm holes on a 10 mm pitch, where the rear sawtooth foot mounts with M3 screws. It also has two 3 x 22 mm battery-strap slots and a hollow, ribbed pedestal 16 mm tall that holds an SG90 servo lying on its side. The servo sits between cradle walls 23.6 mm apart and is clamped through two M3 brass heat-set inserts in 4.0 mm bores. Two 3.4 mm deck holes take the idler pivot post with M3x12 screws and nuts.
