Major rework of the original RPi Modular 2U Rackmount module mount to hold a Ring Bridge Hub of which I created the mountable casing for.
Have also included an embossed Ring logo on the front of the module, along with LED light tunnel holes for WiFi and Link status LED's. I happened to have some solid plastic piping 3.6mm in diameter lying around, which works fairly well as a light pipe/tunnel. More photos of the final printed design in service will follow.
I printed using PLA with 0.2 layer height, 15% infill, 5 walls, and supports on build plate only.
As a side note, but still fully compatible, I am actually using the Raspberry Pi 4 19" 2U Rack Mount v2 frame by @commputethis, which is modified from @scaytrase's original model.
The author remixed this model.
The rackmount module was a major rework of the original RPi Modular 2U Rackmount that I used to create my first design to hold a Blink Sync Module 2.
My rackmount module design was repurposed again here with slight modifications to hold a Ring Bridge Hub which I created from scratch.
