There are many different mounts available, but I was missing a clean and simple design for a x-axis Raspberry Pi camera mount.
Designed for the Prusa I3 MK3, the arm mounts directly on the x-axis with a single M3 x 10mm screw from the spare parts. Using two counter arcs reduces the vibration of the camera significantly. The arm includes a cable management channel for the cameras flat ribbon cable that feeds directly back to the printers x-axis cable management. You can use the cable hooks (https://www.thingiverse.com/thing:3102051) to connect the ribbon cable to the x-axis cable management.
The camera case is designed for the Raspberry Pi Camera Module v2 and uses a simple snap fit case. The camera case is connected with a snap fit ball pivot to the arm, which allows to adjust the horizontal and vertical angle.
Depending on the Raspberry Pi Camera version, the focus of the camera needs to be adjusted slightly. This can easily be done by rotating the cameras lens left or right.
Let me know if you have any improvements to the design.
Please post photos if you make this!
