Tray for 4 Raspberry Pi boards for 19" rack. Takes up 1.5 rack units. Designed for Raspberry Pi with PoE HAT, boot SSD, and a 5-port PoE switch.

Individual cases for Raspberry Pi with PoE HAT, 128GB SSD for booting, and PoE switch for 19" rack.

Heavily inspired by https://www.thingiverse.com/thing:4125055, but fully redesigned from scratch, so dimensions are not compatible.

Print:

• 4 Raspberry Pi cases (compatible with Raspberry Pi 3B+ and 4B) and SSD disk
  (File: raspi_rack19_raspi-ssd.stl)

• 4 trays for the motherboard

• 1 case for switch (model: D-Link 5-Port Desktop Gigabit PoE+ Switch)
  (File: switch_rack19.stl)

• 2 side supports
  (Files: raspi_rack19_soporteD.stl and raspi_rack19_soporteI.stl)

• Use M5 threaded rods cut to 43.5 cm (2 units) and M5 nuts

The parts are designed to be printed without supports. Choose the most suitable orientation (usually face-down on the front opening of the cases). For the side supports, print on the flat side—the opposite of where the rod guides are located.

Exception: the Raspberry Pi tray. Supports may be used here to improve the definition of screw mounts. If so, make sure to remove any tiny supports that may form under the guide ridges, or they won’t fit properly into the main case.

IMPORTANT NOTE:

After several weeks of use, I noticed that in my rack (which lacks active ventilation), the Raspberry Pi units tend to overheat. Therefore, I recommend the following:

• Use ABS instead of PLA, especially for the removable tray where the Raspberry Pi is mounted.

• Install an improved fan activation control for the PoE HAT module, and monitor Raspberry Pi temperatures in some way.

• Use this rack in an enclosure with active ventilation.
