1u stackable Raspberry Pi enclosure

This is designed to be a 1u enclosure for a Raspberry Pi 3/3B+/4 and a 2.5′ HDD or SSD.

Included are brackets to stack two enclosures and arms to mount two in 1u of a standard 19′ rack. The rack arms are designed to offset the Pi’s by 5mm into the rack so there is more room for cable management. I don’t have a 19′ rack (yet) so I haven’t been able to test the rack arms.

The vertical support in the pi and HDD opening is designed to prevent sagging during printing and must be cut out before anything is installed.

The enclosure includes a standard 0.92′ oled display that you can display metrics on. Here’s a link to the script I wrote to display the devices IP address and hostname.

P.S. I’ll post an update with schematics to include a DS18B20 temperature sensor in the wiring harness to connect the oled display to the pi. Have a look at this article that I wrote that includes a python script that sends data to InfluxdDB.

Print settings

Printer: Creality Ender 3v2 Neo
Filament: I used Red Creality PLA filament but I’d recommend eSUN PLA+ instead (Amazon – US, DE)
Bed temperature: 70’c (initial layer) then 60’c for the rest of the print
Nozzle temperature: 205’c
Infill: 20%

Build/installation guide

Step 1 – Use a soldering iron to insert the brass insert nuts. I used a combination of M2.5 and M3.
