Update 1/18/2021: I have added the OpenSCAD source file. Just don't expect anything grand or elegant. :)

This project is for Amateur (HAM) Radio use. You need a HAM Radio license and callsign.

This is a case I designed in OpenSCAD for my MMDVM hotspot project. It is loosely based on https://www.thingiverse.com/thing:2997294 but I designed this one from the ground up. So not a true remix but I still wanted to give credit to the designer of the other case.

This case is designed for the Raspberry Pi Zero W board and a hotspot board I found on eBay, along with a .96" OLED display also found on eBay.

Parts:
1x Case bottom
1x Case top
1x Case frame
4x Standoffs
1x Raspberry Pi Zero W
1x Hotspot board (https://www.ebay.com/itm/For-Raspberry-pi-2018-Latest-MMDVM-Hotspot-Pi-star-Support-P25-DMR-YSF-Antenna/233145671274?hash=item3648909e6a:g:WgcAAOSww4Jcc8Wh)
1x OLED display (https://www.ebay.com/itm/US-0-96-I2C-IIC-Serial-128X64-LED-OLED-LCD-Display-Module-for-Arduino-White/322520336866)
4x M3 25mm hex socket cap screws

It should be noted that the power pins on the display I used are incorrect and need to be swapped when connected to the hotspot board. Otherwise it works great.
04/26/2020 - For the display, I removed the 4-pin header and then soldered in 4 short wires I then used to connect it to the HAT in the correct order.

You will also need a micro sd card, at least 2GB and an image from https://www.pistar.uk/ to make the hotspot work.

I printed both the case top and bottom face-down and did not need any supports. I used black PLA for the thin frame and then white PLA for the case sections.That gives a nice black line along all sides of the case. No supports needed.
