Focus adjustment tools for Raspberry Pi Camera Module 3

I added a Raspberry Pi Camera Module 3 to my Prusa Link setup (Raspberry Pi Zero W), but I was unhappy about the focus of the image. You can easily adjust the focus of the image by turning the front lens. I recommend to start turning the lens clockwise. The initial turning motion may take slight forces as the lens is glued to keep its original setup. After the lens is moving, rotate with small increments until you reach the desired focus.

The adjustment bit fits a standard hex modular wrench. The holding wrench holds the RPi camera in place as you adjust the focus. 

The tools were printed on a SLA printer because of the small details of the adjustment bit. A strong resin was used.
