This is a mock up of the LoRa32 V3 board from Heltec. I made it to test some fitments for a project I am working on and used the official DWG from Heltec to model it. It's a pretty barebones mock up, but it also includes the header pins assuming you have them on there.

Comment if you need me to add a version without the headers.

STEP, OBJ, and STL attached.
