1u Raspberry Pi enclosure with space for 2 x 2.5′ drives

This case is a continuation of my original design of a 1u enclosure for a Raspberry Pi 3/3B+/4 and a 2.5′ HDD or SSD. Have a look at that post for more info about stacking and rack mounting the enclosure.

Parts

• Raspberry Pi 3B/3B+/4B
• POE HAT – this is required because there is no other way to get power to the Pi
• 2.5′ SSD/HDD with USB to SATA adapter (Amazon – US, DE) – for some reason the adapter that I used (linked on the UK and DE stores) doesn’t allow the Pi to boot when it is connected to a USB 3 port which is why I have it connected to a USB 2 port.
• M2.5 and M3 brass inserts (Amazon – US, DE)
• M2.5 and M3 screws and nuts (Amazon – US, DE)
• Micro SD Flexible Extension Cable (Aliexpress)
• DS18B20 Temperature Sensor (Amazon – US, DE)

You can find the .stl’s on Printables here.

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: 60’c (initial layer) then 50’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 M2.5 screws to hold the lid on and M3 on the sides.

Step 2 – Cut off the vertical supports in the Pi and SSD/HDD openings and install Raspberry Pi and POE HAT.

Step 3 – Stack the two SSD’s/HDD’s using the 14mm spacers and 8 x 5mm M3 screws.

Step 4 – Install the drives into the enclosure using 8mm M3 screws and attach the USB to SATA adapters.

Step 5 – Screw on the lid using 5mm M2.5 screws and you’re done!

Last but not least, here is this case stacked with the original design that accommodates 1 x 2.5’d drive and a 0.91′ OLED display..
