I really liked shponglized's case but wanted to use my Raspberry Pi Camera Module with it, so I added a small opening for the camera cable to the case.
I used the Cura custom support plugin to add some support inside the opening. No support besides that.
Update 1 (24. April 2019): I slightly improved the placement of the opening. 1mm to the top. Once I am happy with the print, I will add some real pictures.
Update 2 (24. April 2019): I added a version with a small cable holder on the top. Might make sense depending on you camera placement. You will need to add some custom support to print it.
Update 3 (24. April 2019): Added a version with the cable holder on the side, as well as one with a top and side one.
