Note this was designed for a Raspberry Pi 4.

This is a stackable case design for housing multiple Raspberry Pi's. You could use this case if you were building a cluster of Raspberry Pi's for use with Kubernetes.

You add as many layers as you like, and even expand later if you add more Raspberry Pi's to your cluster.

This design only includes the parts for the case proper and not the parts for the Ethernet switch, USB charger (used to supply power to the Pi's), or accessory mounting brackets.

For these parts please refer to my other design here: https://www.thingiverse.com/thing:4761373
