JX PDI-6221MG - second axis

For my robot project I was looking for a strong and cheap servo motor.
I found the JX PDI-6221MG 20kg but unfortunately this servo has only one axis (horn) so it is not really stable enough for my robot leg.
Therefore I designed this bottom plate with a second axis on the opposite side.

HOW TO:

1.) remove the original bottom plate
2.) insert the M3 nut on the back
3.) screw in the M3 screw
4.) attach your print back to the servo

YOU NEED:

1x M3 screw
1x M3 nut
1x ball bearing
