Raspberry Pi Case and Cluster Files

thingiverse

This design works with the Raspberry Pi B+, Raspberry Pi 2 computer, and also for the Raspberry Pi 3, plus the 3B+. The whole thing is passively cooled from start to finish. You can make a single case for one Raspberry Pi by printing two base boards and four outside clips, or you combine baseboards and locks in various ways to form different-sized Beowulf clusters. For really big clusters (more than 10 nodes), you might find it helpful to have a fan that helps with cooling. This design was initially made for my class on parallel computing. Unfortunately, I didn't end up using these files since the Parallella board became available to buy last July. Check out my other contribution for the Parallella case files for more information. This design let us create a 21-node Raspberry Pi cluster that is shown here - two of my students have used this for their own study projects without any issues with overheating reported by either one. We built a 28-node cluster using just Raspberry Pi 2s, and it was so hot we had to add a fan for some extra help. An 8-node cluster made in 2017 worked totally fine with passive cooling only - the heat didn't become a problem. You should remember that as the power needed from each Raspberry Pi increases, larger clusters might need a fan too for staying cool. Adding another layer of base boards will also increase space and airflow, which is super helpful.
