About this 3D model
This is a mount for the Raspberry Pi to Prusa i3 reprap printer. The Pi is attached to the mount with M3 screws and nuts and the mount itself then clips onto the aluminium frame of the i3. Network your i3 with a Raspberry Pi and Octoprint and a suitable 5v power supply. I added an L78S05CV 2A 5v fixed regulator to the RAMPS 12v supply.
