This is a remix of Wassupdoc's fantastic, minimalist RPi Zero W case.
I slightly increased the height of the case to accommodate the official RPi camera module (V2) instead of the Picam. I made a cutout for the camera module PCB and increased the width of the original channel for the Picam ribbon cable to fit the wider ribbon used in the official camera module. Like with the original, the ribbon is intended to be sandwiched between the camera module and the RPi board.
I also made an additional backplate with a cutout for better access to the GPIO connectors. Have not tried installing any header on the board.
Due to the increased height of the assembled case the holder was also slightly modified.
Note: The fit of the pins is really tight so be careful when inserting the RPi board. Also the HDMI connector might be obstructed depending on your cable and connector. If you intend to use it, take this into account.
Also the camera module will end upside down, so remember to correct that in your Octopi settings!
