This model fits the E1 Zoom/Pro with a diameter of 84 mm.

For the 76 mm version you can use [https://makerworld.com/de/models/2230670-reolink-e1-76-mm-riser-variable-height#profileId-2426895](https://makerworld.com/de/models/2230670-reolink-e1-76-mm-riser-variable-height#profileId-2426895)

The riser lifts the camera and angles it downwards at 30°.
The camera is held in place without screws; the risers are completely pluggable and can be combined to the required height.

The first profile contains a 14 cm base, an 8 cm riser, and the camera mount.

The second profile also includes a smaller base (10 cm) and risers in heights of 3 and 5 cm.

The mount has a central hole; if the camera is too tight, you can use this to push it out. This was an issue I encountered with the first versions, but not with the released V3. 🙈

I have added the STEP files 

Note: the necessary supports can be removed very easily and without leaving any traces once they have cooled down sufficiently.
