This is a work in progress. I have not printed this yet (waiting on filament) This should fit the 10 inch rack with minimal fuss. As the title and summary say, this is a standard 10 inch panel that was remixed to hold a Raspberry Pi 4, and a Gl.iNet Beryl AX router.
Thank you to the original creators for their work.

The author remixed this model.
Hacked and merged until I got a 10 inch panel for a Raspberry Pi 4 and a Beryl AX router
