ESP32 Camera X-Motor mount for Prusa MK4 / MK4S with articulated arm

Updated on 2nd November 2024

• deleted the horizontal version because it is difficult to print
• using the Articulated Arm Swivel Joint the horizontal version is obsolete
• made the USB cable channel 1mm deeper

I wanted to attach the ESP32 camera to the x-motor so that it is always at the same height as the nextruder.

I am using the Prusa original enclosure and the MMU3 unit with all 5 filament spools inside the enclosure, so the space for mounting the ESP32 camera was limited.

In addition, I wanted to route the camera's USB cable so that it could move with the x-motor and be protected.

Therefore i remixed the x-motor cable protection from @dancan13f and added a mount for the articulated arm from @MichalFanta

To route the usb cable to the camera i added a channel (diameter 4mm) through the x-motor cable protection arm

For printing and assembling the remixed x-motor cable protection see the original description

Choose your desired joints of the articulated arm and swivel joints to build your arm.

I also used the camera case from @MichalFanta

Be careful when tightening the printed screws on the arm, they are very tight in the thread. You should print the screws with a scale factor of 98% for easier fit.

Below my own version of the camera mount and the used parts:

The X-Motor Cable Protection Part with the Articulated Arm Mount, mountable to the X-Motor with a M3x18 SHCS screw

2x 360° Swivel Joints, assembled with a M3x12mm screw and a M3 nyloc nut.

Be careful when inserting the screw not to break the joint wings
