This is a support for a Raspberry Pi (B+, 2, 3) and a relay for the Ultimaker 2.
The idea is to install OctoPi on the Raspberry Pi and control the 3D printer remotely. The power to the printer can be turned on and off remotely (instead of having to toggle the button behind the printer), so the Ultimaker extruder fan does not work all the time. This part will hold the Raspberry Pi and relay under the printer, hidden from view.
The support is full of holes in order save plastic and avoid it curling up on the edges.
The printer will remain usable just like before and should not void the warranty (unless you mess up something).
