Summary

This is a stackable case for the raspberry pi that allows you to create a blade center type setup or you can mount one of these cases in a standard 5.25 PC mount and have a Pi in your PC. I've included an, untested, rack mount end plate that will allow you to mount this in 4U of space

Instructions

EDIT:Uploaded an plate that should allow you to mount this into a standard 19 inch rack. I don't have a rack to test this on though, so let me know if it doesn't work out.

This case prints in two pieces, the receiver and the carrier. The carrier holds the pi, the receiver holds all of the cables. The idea is to have the receiver setup with all of your accessories, power and ethernet plugged into it. The carrier can be docked and undocked and holds itself in place using the pi's usb and ethernet ports. Power is supplied via a standard molex PC power supply and a 5.5mm barrel jack from a CCTV setup. You can print multiples of these and attach them top to bottom to create a blade center of sorts. Just use the PC mounting holes and a bit of plastic to join them together. Source 123d files available in my github https://github.com/scratchhax/3DPrinting/tree/master/Blade_Center
