1. Step: attaching the unihedron to the holder

Please remove to original 4 screws, which close the package of the device from the button. Put the device upside down below the holder part and use the 4 self cutting screws to fix the unihedron to the holder.

3. Step: attach the two drew shield rings

The OTA ring with the nose should be on the upper side of the OTA the second on the lower side. Use two M4 screws to tighten the connection. As I used PETG, I did not need a thread nut. please check this in your case. The OTA ring should be directly linked to the drew shield end.

4. Step: attach the holder to the dew shield ring nose

The holder slips exactly on the nose of the dew shield rings.
