Update 2021-01-23
Added an X motor/endstop mount with a vertical cable retainer, "X motor cap cable clip_2.stl".
Added a longer camera arm. Slightly thicker support framework to allow for more slicer variations. "X_camera_arm-long.stl"

Update 2021-01-25
Added an extension that also adds an extra joint.
The original arm with the extension is about the same length as the longer arm.

Added a longer extension piece.

As many of you know, OctoPrint is a fantastic piece of kit, especially together with the OctoLapse plugin.
I found that securely mounting the camera while it not being in the way was not as easy as I thought, hence this design.

The nice thing with this approach is that the camera follows the Z-axis, which is kind of important on a printer with a tall Z.
A static camera installation will not follow the recently printed layer and would be just right for only a few layers of the print.

The thing consists of two parts, one that replaces the X axis motor/endstop mount and the arm itself.
Both parts are easy prints that doesn't need supports.

The arm has two mounting holes at the end, 3 mm and 6 mm, allowing you to mount most cameras. If you need more mounting points there's space to drill out a few more holes.
You can mount the camera either on top or under the arm.
I prefer the images generated with the camera at a lower position.

See image on how to plate the prints for best results.

Designed for the CR-6 SE/MAX, but the Ender 3 line of printers uses the same endstop cap, so it should work there too.
