This design mounts a Raspberry Pi Camera V2.1 onto the 2020 extrusion on the back side of my Ender 5 Pro using a T-nut. The design has two angles of rotation, one with the T-nut and the other one with a pivot screw.

The design needs the following extra parts:

• 1x M4 Nut (normal)
• 1x M4 T-nut
• 1x M4*10mm screw
• 1x M4*30mm screw
• 4x M2*10mm screw

The camera is mounted into the case using the 4 M2 screws. Before connecting the camera to a Raspberry Pi, make sure you first slot the ribbon cable through the designed slot in the extrusion holder. The M4*30mm screw and the M4 nut connect the camera case to the extrusion holder and act as a pivot axis.

As to how the actual view onto the print bed is, I attached an image because I missed the actual view in a lot of other designs here on Thingiverse.

If you want to change some dimensions yourself, I attached the FreeCAD file.
