Raspberry Pi 3 and Arducam mount for Ender 3 - No extra hardware needed

This is a Raspberry Pi 3 + Camera mount for aluminum extrusions used in most 3d printers. I didn't find any that fit my requirements so I made one.

• Most parts prints with no support, and where it's needed support is minimal.
• No extra hardware to fit and mount the parts.
• No extra hardware to mount the RPI. Just slide it into place and go.
• Designed around the inexpensive Arducam, the pi & camera mount accommodates the short 6" ribbon cable it comes with, eliminating the need to buy a replacement.
• The camera mount uses ball Joints that are printed horizontally. They require no support, and if you have good bed adhesion no brim either.
• Horizontally printed ball joints are stronger and less prone to breaking than vertically printed ones, allowing for tighter tolerances and a more snug fit.
• The camera mounts to a 2020 v-slot by way of a twist mount, you can mount it just about anywhere.

Since Printables doesn't allow the uploading of .wings files you'll have to make do with STL. There's a MK2 version of the Pi mount that uses twist on pieces to secure it. It means the Pi can be mounted almost anywhere and doesn't need an open end of an extrusion to slide into at the cost of needing a flathead screwdriver.  SCAD files for the MK2 are included. 

Notes:

• Minimalist RPI 2020 Mount will probably need supports and a brim. The rest should not.
• If you need more extension bars just print more. After 6 or so the camera can get a bit wobbly.
• Make the prints solid, but use more walls instead of more infill. The more walls that get printed the stronger the ball joints will be.
