About
This is a small gripper for 180° micro servos, such as the Tower Pro SG90. The gripper works by using a rack and pinion to move one of the gripper arms.
The gripper is easy to assemble and only requires one screw. The micro servo clips into the gripper. The gripper has screw holes for attaching it to other parts or surfaces.
Parts
There are three parts to this project which need to be assembled together post printing. Only the spur gear requires a M2 screw to attach it to the micro servo.
- Pinion gear
- Gear rack
- Servo mount
Assembly
The micro servo need to be set to 180° before the servo is attached to the gripper. The rack should placed on the servo mount with the gripper arms in the closed position. Then clip the micro servo to the gripper.
