Gripper Servo Palm
This palm is part 6 of the 'SG90 Four-Axis Desktop Robot Arm' kit. It is a 65 x 52 x 5 mm plate that holds the gripper SG90 servo in a 28 x 12.6 mm window with M2 ear slots, which puts the drive-jaw axis at (-10, 0). The M3 idler-jaw pivot runs in a 3.4 mm slot with 5 mm of travel on a raised 2 mm washer pad, so you can set the 20 mm gear mesh. The palm bolts to the forearm tip with two M3 screws through Ø3.4 holes 15 mm apart.
