OPE-compatible magnetic ball mount for RPi Zero 2 cams

This is a magnetic ball mount. The diameter of the ball is 16mm, so this should fit any models based off of the RPi Camera Holder Plumbus. If you have an Original Prusa Enclosure it will fit neatly in the corners.

This model supports eight fully enclosed 6x3mm magnets. The chambers for the magnets are 7x4mm to allow for minor variations in the print.

I use it for a Pi Zero 2W-based camera in my OPE so that I can change the camera elevation as needed for each print.

What you'll need to make your own camera mount:

• Raspberry Pi 2W
• 12MP IMX708 Camera Module 3 for Raspberry Pi
• This excellent Prusa Connect camera script
• This ball mount 
• The back panel: Ball hinge Back Panel Camera Case for Raspberry Pi Zero 2W 
• The V3 camera case bracket and camera case lid: Original Prusa Enclosure Raspberry Pi Zero 2W Camera Case

Material: 

• PETG
• Default: 0.15 mm STRUCTURAL 

Layers and perimeters: 

• Enable "Thick bridges" (Normal mode)

Infill: 

• 15% infill 
• Rectilinear pattern 

Slicer: 

• Add a pause at 5mm

You can ignore the print stability warning. PrusaSlicer doesn't like the chambers for the magnets, but thick bridges will give them some support. This is the rare case where it's ok to be ugly on the inside.

When it pauses, drop the magnets in the holes then restart to seal them in. *Make sure the magnets are aligned and not fighting each other!* The easiest way to do this is to create a 2x4 pattern on a refrigerator or the enclosure so they are not repulsing each other, and then insert them in that order.
