Raspberry Pi vertical rack with router

I needed a stand-alone rack to mount 4 raspberry pi4 vertically and house a basic ethernet POE router

Inspired by https://www.thingiverse.com/thing:4125055 and I used the same trays

There are files for double racks to fit 8 pi's, and also rear covers for fans, which we found we don't yet need.
Enjoy, and please hit the LIKE button so I know there's intelligent life out there. If you like my work that much please feel free to tip

Update: Added Pi Rack single with braces. Stops the rack from spreading if you print it from PLA
