This is a remix of this sleeve case for the raspberry pi. I made the 2 additions of a mounting bracket and a pi camera ribbon cable opening. These changes were made so I could easily mount my pi to my Maker Select to use with Octoprint.

I used 50% infill for strength. I'm sure 20% or so should work as well but 50% only takes a few minutes more.
Adding the Camera to the Pi
It can be a bit tricky to get the ribbon cable seated. What I did was have the cable connector slightly open when sliding the pi into the sleeve. Once the pi was fully seated I connected the ribbon cable through the cable opening and closed the connector with some small tweezers.
