I wanted to rack mount my collection of R-Pis in in half height 19 inch server rack alongside my full-sized servers. Existing models didn't cut it, as they either didn't span the entire 19 inch rack or had too much unused space. So I opted for a 2U height, allowing me to rack 10 Rasberry Pis in a single "enclosure". Giving me plenty of room to expand in the future.
The rack itself is segmented the mount into smaller parts to allow easy printing on smaller printers. The rack parts can be glued together with CA glue. They can also be pre-assembled in your slicer if your printer is large enough to handle 483mm in a single direction.
The Pi "Blade" can be slid in and out easily with the hook. The hook can be printed separately and glued in place with CA glue, or attacked to the Pi Blade in your slicer and printed as a single unit.
Blanking plates are included to fill up unused slots and maintain proper airflow in your rack.
In the future, I may add a section to the back to allow easy docking and undocking of cables if I can find a suitable set of angled cables to attach to the Rasberry Pi to facilitate a smooth docking experience.
I used CA glue to use connected the left, middle, right, and insert panels together. Once the glue set, I mounted them to my rack using standard cage nuts and rack screws.
Designed in Fusion 360. The Pi Blade component was remixed from another maker's Rasberry Pi enclosure. Though I can't seem to find the original listing, so if you recognize it, please let me know so I can provide proper credit.
