I made this as a temporary mounting bracket for debugging and beta-testing an unusual pi-based project that involves using a SIM7600x module (providing 3G/4G data and GPS to my build).  If anyone else has use for it, you're more than welcome to use it.
 

The mounting holes are NOT threaded, they are designed for use with m2.5 heatset inserts.

When I finish the project, I'll share the models for the final product's printed components along with a list of the parts I bought (with links) and links to build-critical software/source code.

The project may take quite a while as the spare time I use to work on this project is spread rather thin amid all the other things I'm doing right now.

No photos at time of posting (still printing)  Will update when completed.
