A simple case I designed for housing a Raspberry Pi Zero W. Following [this tutorial](https://www.reddit.com/r/ElegooMars/comments/jxhyi3/using_a_pi_zero_w_as_a_smart_usb_flash_drive_for/) I was able to set up my Pi as a Wi-Fi enabled smart USB mass storage device plugged into my Photon Zero 3D printer. This allows me to "wirelessly print" files by dropping them in my Pi across my network.
The case itself is to help protect the Pi from any potential spills during set up on the printer. It features holes on the backside of the case for gluing small magnets. This allows the Pi to stick to the side of your printer if the printer is metal like mine. The holes are sized for 10mm diameter magnets 2.5mm thick. There is ample room on the USB ports for any size USB cable or charger. Additionally, there are vent slots and raised mount pegs to help the Pi stay cool, not that it should be heating it up a ton. All of the screw holes are designed to use #3 screws. I highly recommend buying self threading screws designed for plastic, otherwise you may break the mount pegs or sides of the case when screwing them in.
I hope this can be useful for anyone who needs it. If you have any ideas to improve the design, I'd love to hear them. I am a rookie when it comes to CAD modeling.
