60kg Servo Adapter for U-bracket DS5160 SSG

this is a new bottom cover for the big 60kg Servo DS5160 SSG to get a u-bracket as it is almost impossible to buy these servos with the right brackets, even though they are offered with them everywhere. when you receive the package you will notice ... no brackets :(

This design should solve the problem so that you can equip your 60kg servos with u-brackets and use them for robotics projects or the like.
The counter horn is equipped with a standard skateboard-bearing.
an M8 screw serves as the pin.
the flanges (right word?) are made from 2mm aluminum plate
everything is screwed together with M3 and nut-inlays
 

EDIT:
Please note that the gif is no longer up-to-date ;)
I changed the counter-horn and added two spacer to get the full advantage of the ball bearing
if you have suitable metal washers, you should use them. the following pictures should explain the assembly of this part:

as the top cover is much more complex with all the gear and bearings, I decided to leave it like this and add a little adapter instead

first tests showed that it is promising and rock solid
I am looking forward to your feedback.
