After designing my External Spool Holder for Prusa XL Enclosure, I realized that the official model for the Buddy3D Camera mount prevents me from using them. I also wanted to try to rotate the mount point slightly in order to get the camera at a better angle relative to the bed and harness for extruder 1 (in retrospect, I'm not sure if it makes much difference).
XL_Twist_lock.stl file from Prusa's official Buddy3D Camera mount There are two versions of the file:
You shouldn't need to do anything special to print this. The overhangs are set to a max of 30° and print great in PETG or PC-CF with the 0.2-structural preset (though I'd recommend switching to adaptive cubic infill that provides a bit more reinforcement of the perimeters).
As with most of my models, you can find the parametric CAD at onshape.
The author marked this model as their own original creation.
