I purchased this board. https://www.aliexpress.com/item/1005003515392256.html (without the screen).

I couldn't find a case that I liked for the MMDVM_HS_Dual_Hat so I designed one for the Raspberry Pi 4.

STEP and STL files are included if you would like to make any modifications to the model.

I assemble mine with 4x M2.5x22mm screws. M2.5x25mm will also work. These are the ones that I use. https://www.amazon.com/dp/B07PPC173T. I use the same screws for my other Hotspot case.
