Summary

I have been had a thought that to rebuild my eagle tree antenna tracker for a long while, and finally, I made this. I have two old 6000 series bearings, dD 10mm x DD 26mm x W 8mm. And I plan to use the tilt part from https://www.thingiverse.com/thing:2994928. Feel free to leave a comment if you have any question.

I use two MG995 servos and their dimension looks very similar to HS-8335SH, so I guess it gonna work by using that tilt.

It works. I got two small bearings from two old 2212 motors(dD3mmDD8mmW4mm). new "circle.STL" is for the small bearings to mount on the tilt, by one 3mm screw. so does the "servoarm.STL". Last, my ugly flat antenna uses "antmount.STL" to mount on the tilt. I would say, when I try to mount the servo to the tilt, the wire stucked, so I disassembled the servo in order to make the wire pass through the tilt. I may make a compact one for the 5.8G systems.

For more accurate, I recommend 0.2mm layer for the smaller components.

Be aware, don't mount the adapter upside down, or it will be unstable.
