As title says, this is housing for RPi Camera with HDMI to ribbon adapter. It is made to snap hold the RPi cam + HDMI adapter assembly in the case. The lid is snap hold only too. Its is pretty tight and hard to remove, so make sure you are ready to commit.
The mount is made to fit the Prusa MK3 Camera Bed Mount Arm
The reason to make it all snap fit is because the screws, nuts and stand offs that come with the adapter are made of nylon and are not able to cut threads into printed parts. I am also minimalist and I hate bulk, so the case is made with no room to spare and with exposed HDMI port.
Added bonus is the attachment to Prusa i3 MK3 Einsy/Rambo housing. If you use RPi Zero with your Prusa, this will keep the other end of HDMI to ribbon adapter in place. I used 3 feet hdmi cable for perfect fit.
