I printed with PETG but it can be printed with most anything. Some parts need support to print. I also use a brim. The support is minimal.
This is a work in progress so I need to finish placing the countersunk screw holes in the mounting base.
I realized that I have drawn this for the sainsmart NOIR camera so I will add a version 2 that is for the official Picam.
I used m3 8mmstainless button heads all around except two black socket caps for the rpi because they are cheaper and a stainless socket cap m3 20mm on the base. The camera housing to base connection is an M4 20mm.
