Raspberry Pi 4 Modular Stacking Cluster Case

thingiverse

This is a perfect case for the Raspberry Pi 4, enabling you to build a cluster of raspberry pi's by stacking cases on top of each other. The thumbnail showcases three but you can stack as many as you want. Each middle layer clicks into place above and below it. Once you've built your stack, simply add a top and bottom to secure everything in place. To be clear: You can print out as many middle layers as needed, then cap the stack with a single top and bottom. EDIT1: I reuploaded the STL file with an additional part that allows air flow to the bottom Pi. I also renamed the main stacking module to "middle." Credit goes to user IGV2016 for suggesting the addition of a bottom to the stack to improve airflow.
