19" (1U) Raspberry Pi Server Rack Mount

Simple and cheap (but very useful) 19" rack mount for Raspberry Pis. Extra required parts are:

• 4 x 10mm M3 Screws (4 per caddy)
• 4 x M3 Nuts (4 per caddy)
• 8mm x 450mm Aluminium Rod
• (Optional) Super Glue

I bought my rod from a local hardware store, it cost about £5 for 8mm x 1000mm. I offered this up to the 19" opening in my server rack, marked it and cut it down. 1 x 1m rod is fine for one of these rack mounts (multiply as necessary).

I've designed it so the rods push fit into the ear however, you may use a dab of super glue to make it extra string.

You can fit 5 - 6 Pi's in 1U of space if you use right angled power adapters. In my case, I can only fit 4 because of the protrusion of the power cables.

The caddy design allows you to pull the Pis out for maintenance without the need to disassemble the whole thing.

Inspiration

I've seen many awesome attempts at a rack mount system for the Raspberry Pi however, most of them take many hours and material to make. I wanted to design something cheap and simple. You can print the ears + 1 caddy in just under 2 hrs.
