Introducing the Prusa XL Cam mount using the Buddy3D Camera from the CORE One. 

I have been trying several solutions to add a working camera to the Prusa XL but the ESP32 cam's kept hanging up or just didn't work reliably then it struck me, don't reinvent the wheel just use something that already works so enter the Buddy3D camera.

After several revisions, tweaks, adding features and setting the best camera shot, I am happy to present my solution, the Prusa XL cam mount.

Simply remove the existing back panel from the Buddy3D and add this mount using the same screws from the original panel. 

The only additional hardware needed are two 10mm X 3mm neodymium round magnets, one 4mm hammerhead nut, one 4mm X 16mm socket head screw, small piece of VHB tape, and two small zip ties.

The magnets should have just a little snug fit but I also left a little space in the bottom of the pocket for a dab of super glue.

Add the small piece of VHB tape top the shown tab.

Route the USB cable from the camera through the hole, behind the tab and zip tie as shown.

Install the 4mm socket head screw and hammerhead nut, remove the tape on the VHB and slot the assembly onto the arm pressing on the front to set the VHB into position. Then tighten the 4mm socket head screw while carefully watching not to pinch the USB cable as it existing the mount.

Printing suggestions.

• Use organic tree supports build plate only
• Use four perimeters at 0.2 layer height
• If you don't want the text just assign everything to tool one.

Enjoy and happy printing!!
