Customizable Pinion Puller

Very simple customizable gear puller mainly for small motors.

#####Non-printed parts needed

• bolt + nut (default M4)
• something to push motor axis - I'm using very small hex key bit

#####Parameters

• hole_d = diameter of the hole for motor axis
• space_x, space_z = size of inner room (space_x * space_x * space_z)
• grip_t = thickness of the side gripping the gear
• side_t = thickness of the side walls
• nut_d = size of the nut measured across the angles of hexagon (default is fitting M4)
• bolt_d = hole for bolt (it should go through freely)
• pusher_d, pusher_fn = hole for pushing part - I'm using hex key bits so d is size of the bit across the angles and fn = 6 to get hexagonal hole
• joint_h = height of the joining part
• joint_minimal_t = minimal wall thickness of joining part
