Introducing the 5 inch micro server rack! This 5" x 5" server rack is designed to hold smaller networking or computing equipment and sit neatly on your desk.
 

Overview

I had a Raspberry Pi 4B and a small five port network switch sitting on my desk and decided that I wanted to clean up some desk space. Existing server rack sizes were 10-19 inches wide, which were much too big to sit on my desk. So I decided to make the smallest one possible! The limiting factor in this design is my TP-Link network switch, which is just about 4" wide, and it just about fits in the server rack.

This is v1.0 of this server rack, and features only a few attachments (tray, network switch, and Raspberry Pi). Please let me know what other attachments you would like to see!

NEW: Raspberry Pi 3B/3B+ Case is now availble on Makerworld

Requirements List

The following items are required to construct this server rack:

Printed Parts:

• 3U Micro Rack x4 (one build plate)
• Micro Rack Lid x2 (two build plates)
• [Optional] 1U Micro Rack Tray x1 (one build plate)
• [Optional] 1U TP-Link TL-SG105 Rack x1 (one build plate)
  [Optional] 1U Raspberry Pi 4B Rack Top & Bottom, x1 each (one build plate)

Purchased Parts:

• 8x to 20x #10-32 x ¾ in Machine Screws and Bolts
• [Optional for Raspberry Pi] 4x #6-32 x 3/4 socket head cap screws
• [Optional for Raspberry Pi] 4 x #4-40 x 1/4 socket head cap screws
• [Optional] TP-Link TL-SG105 Network Switch, or similar sized network switch

Assembly Instructions

Assembly of this server rack is quite simple:

1. Use four of the #10-32 machine screws to attach the four 3U arms to the one of the lids to form the base plate
2. Use another four #10-32 machine screws to attach the other lid as the top of the server rack
3. [Optional] Place the Raspberry Pi into the bottom case and then use the #4-40 screws to secure the Raspberry Pi in place
4. [Optional] Place the top of the Raspberry Pi case on and then use the #6-32 screws to secure the case
5. Slide in the rack units (Tray, TP-Link Rack, or RasPi 4B Rack) into your location of choice in the server rack
6. [Optional] Slide the TP-Link Network Switch from the side of the server rack, since it won't fit through the front
7. Use the remaining #10-32 screws to secure the rack units into place. Some effort may be required to push the screws through the holes since the tolerances are tight
