3D Printed Raspberry Pi Rack Mount with Heat-sink (Passive Cooling)

With now 6 Raspberry Pis lying (hanging) around inside and around my server rack I’ve started to look for a nice and clean way to mount them in my server rack. On thingiverse I’ve seen a few 3D printed Raspberry Pi brackets and I immediately liked the idea; but as I wanted a simple design with the ability to add a heat sink, I had to start from scratch. Also, at the time I started the design, there weren’t any brackets for the newest Raspberry Pi 4. So, the result of my effort can be seen here:

After a about half a dozen iterations over the last two months, the following 3D print is ready to be equipped with heat sinks and mounted in my server rack:

I’ve prepared two versions of the RasPi Rack holder, one for the the older Raspberry Pi 3 Model and one for the Rasperry Pi 4. The STL files for 3D printing are available for download and licensed under CC-BY-SA 4.0: RasPi_RackMount.zip

The heat sink was bought on ebay (link) and is the upper half of a passive cooled aluminium Raspberry Pi case.

The 2 HE rack panel was bought at Musicstore.de, but I’ve also seen them on ebay and Amazon. They also sell small panels to cover 1 or 2 empty slots, if necessary. The 2 HE panel can take up to 10 modules (i.e. Raspberry Pis).

The RasPi’s are currently all powered from the back side, each with their own power supply. I’m currently planning on inserting a 5x USB charger into one of the module slots to power up to five at the same time.
