1U Rack Mount for up to 5 Rasberry PIs .

Options for partly 3D printed / CNCed and fully printed (Images are from my part and part version).

Blanking plates and a POE power supply trays included. 

The pin is only required for the printed version, its slides into a slot at the middle back to stop the dove tail from coming loose.

Depending on yout printer the dove tail joint may be very tight, hammer it in if required, tight is good.

Fusion files included for the CNC version and tool paths (If Makerworld will accept them)
