Modular Raspberry Pi 3/4b Rackmount

I designed this Raspberry Pi rackmount tray to use with my small home lab, and I hope you can find a use for it too! I included four versions (two for each Pi board) along with a fan bracket to mount a 120mm fan to the side of a cluster of two Raspberry Pis. There are files with and without the SD extension slot to fit your hardware best. It mounts from the left side of a server rack. It is also designed so you don't need to use any screws, and the Pi will just click into place! It's designed for the Raspberry Pi 4b and 3b models.
