I’ve published a couple of simple 3D printing projects which may be useful for others:
- Mount for the Leo Bodnar mini-GPS units:

- Mount for the W1GHZ dual band (10 + 24 GHz) feed horns:

You can download the STLs and print them, or get them printed. I’ve also included the STEP files so they are easy to modify or fabricate via other methods. They’re Open Source licensed (see the repository for details).
