Raspberry Pi 2U Rack Mount (19” and 10”) – PoE or USB

I have been using russross’s 1U design up to this point (Raspberry Pi 4 1U rack-mount bracket by russross found at https://www.thingiverse.com/thing:4125055 or https://www.printables.com/model/458627-raspberry-pi-4-1u-rackmount-bracket ). It is a great design.

When I needed to add more Pi’s, I knew I would move to his 2U design. However, I felt that I could “trim” some time and material out of it and keep his original concept. So, I am posting this as a remix. (It uses roughly 25% less filament.)

The individual Pi frames have been eliminated by creating a front and rear rail. On the 19” rack version, spacers provide stability between the #10-24 threaded rods. 

There are 3 and 4 bay versions (just for fun) if you wanted to add some color with the spacers. The original design’s Pi tray is still used (it is included for your convenience). Each bay is 33mm wide providing enough height (clearance) for the official Raspberry PoE HAT on a Pi 3B+ or Pi 4. 

I made a couple different bay blank plates if you decided to “close up” the front or use some of the bays as cable access through your rack.

There are also ears with 2 or 4 mounting holes based on your preference.

Also included is a 10” rack version that can hold 3 or 5 Pi’s for those of you using the smaller half racks.

After purchasing a Pi 5 and adding a GeeekPi PoE+ Hat w/NVME, I found that the bays do indeed need to be wider to accommodate the additional height. I added some rail versions with wider bays – these can be mixed and matched with the other rails (depending on size) to make various configurations. Rails are now labeled with 105mm and 141mm width – so you can easily mix-n-match front and rear rails. These rails are for the 19" PoE version ONLY.

Added 10" version with 3 wide bays to accommodate Pi 5 with GeeekPi PoE+ Hat w/NVME. These rails are for the 10" PoE version ONLY.

NOTES:

• The PoE versions have less depth and are designed specifically for PoE, the Pi’s USB power connector is NOT accessible.
• The USB versions are a bit deeper and are designed for use with a USB power supply, the Pi’s USB power connector is accessible. (Obviously, it can also be used for PoE as well.)
• The frame parts are sized for a #10 threaded rod. The frame is stable with #10 threaded rods; I did not see the need to go with a larger threaded rod.
• Please measure the distance between your rack rails to be sure this will fit in your rack - it will be tight going into a populated rack. I have included ears for both versions that will add 2mm more clearance to each side (allowing for slightly shorter threaded rods than noted below).
• Printed parts – no supports, I recommend 0.20 – 0.24 layer height, 2-3 walls, 10-15% infill

19” rack printed parts:

• 3 or 4 front rails (based on configuration)
• 3 or 4 rear rails (based on configuration - PoE or USB version)
• 2 or 3 spacers (based on configuration - PoE or USB version)
• 2 ear brackets (2 or 4 mounting holes - PoE or USB version)
• Bay blanks (as desired)
• Pi trays

19” rack hardware:

• 2 - #10-24 threaded rod. I recommend buying two 36-inch rods, which is enough for four finished parts, assembling the parts, measuring (after nuts are installed) and then cutting the rod to make it as short as possible (approximately 17-5/8” (448mm)) so that it clears the rack when inserting it. 
• 8- #10 hex nuts for the threaded rods.
• Necessary hardware to mount the Pi’s to the trays.

10” rack printed parts:

• 1 front rail
• 1 rear rail (PoE or USB version)
• 2 ear brackets (2 or 4 mounting holes - PoE or USB version)
• Bay blanks (as desired)
• Pi trays

10” rack hardware:

• 1 - #10-24 threaded rod. I recommend buying one 36-inch rod, which is enough for four finished parts, assembling the parts, measuring (after nuts are installed) and then cutting the rod to make it as short as possible (approximately 8-5/8” (219mm)) so that it clears the rack when inserting it.
• 4 - #10 hex nuts for the threaded rods.
• Necessary hardware to mount the Pi’s to the trays.
• Optionally, you can choose to eliminate the threaded rods and tap the frame holes as noted in the make comments by FireFly at https://www.printables.com/make/2406889 

The individual Pi frames have been eliminated by creating a front and rear rail and utilizing spacers for support on the 19" version.
