This is a remix of Amanno25's Raspberry Pi Zero Camera Case that works with a RPZ that has the GPIO pins already installed. this fits the RPZ and camera perfectly, however, I would recommend putting a piece of electrical tape on the back of the camera as it ends up sitting on the GPIO pins and I would be afraid it may short something out. I haven't tried it without the tape, but I take no responsibility if you don't use the tape and it fries either your Pi or the camera.
EDIT: I've uploaded 2 different stands, one that is upright and one that is at a 45* angle. I haven't tried printing either of these yet, so they may need some adjustment, but I've taken the measurements off my print and used as a basis. I'll update here as soon as I've printed them and tested.
