This is a mini-server rack with equipment trays for:

• Philips hue hub
• IKEA Tradfri bridge/hub
• Dual Raspberry pi 4B
• Dual Raspberry pi 3B
• Lutron Caseta hub
• TP-Link TL-SG108E Smart switch
• Anker Powerport 6-port USB power supply

In order to assemble, you will need:

• M5 nuts for frame
• M5x10mm screws to hold equipment trays onto frame
• M5x12mm screws for frame rail couplers and feet
• M3 nuts for caseta and hue hub tray; TP-link switch tray
• M3 x 8mm screws for caseta and hue hub tray
• M3 x 12mm screws for TP-link switch tray

Everything can be printed on an Ender 3 build plate up to the 4U frames (some things must be turned 45degrees).

All of my devices are 5V powered so I used the Anker Powerport 6-port USB power supply to power the entire rack from one mains outlet. I used:

• USB-A to 5.5mm x 2.5mm barrel plug cable for the philips hue hub
• USB-A to 3.5x1.25mm barrel plug cable for the TP-link switch
• USB-A to USB-C right angle cables for the raspberry pi's

This is a standard “10in half-rack” with standard unit height of 44.5mm. Find reference dimensions here: https://upload.wikimedia.org/wikipedia/commons/8/84/19_inch_vs_10_inch_rack_dimensions.svg

I printed mine of PLA (protopasta HTPLA Empire strikes black), 3 walls, 15-20% gyroid infill, supports where needed.
