Raspberry PI Multi Rack

This is 4x Raspberry Pi Holder with the ability to swap and power from within the case. I have looked and tested around and the model works with all standard raspberry pi's. YAY. I have been successful in mounting a raspberry pi 3b, and a libre compute board (le potato), as they all use the same mounting and size dimensions. NOW UPDATED FOR RASPBERRY PI 4 AND 5! I have also included links for used hardware at the end of the description. I have made mounts and parts to hold the USB power supply and network switch via a friction fit. The addons for the power supply and switch are their own stand alone parts so they can be added independently. To add them on I just welded them together with a soldering iron but glue would work just fine. I plan on adding active cooling with 60mm Fans via usb power in the future. For the inserts I used the m2*2*3.2 sunk in with a soldering iron and m2x4 or m2x8 screws. You need 3 brass inserts and 3 screws per pi. If you like the model please support,
