The recommended way of connecting the UFD to the O'Tilter is by using the four long M2.5 x 20mm screws provided with the UFD.
You should connect the O'Tilter first to the camera.
After the O'Tilter is properly connected to the camera, you can connect the UFD.
In case you wonder, four screws are sufficient to hold this part firmly in place.
TIP: If you use an OAG, the focuser of the OAG may interfere with the filter's extraction from the UFD. Positioning the UFD at an angle that will allow you to extract the filter drawer easily may be convenient.

Note: Do this only after you have connected the O'Tilter to the camera. For clarity, these images have been taken without the camera.
