CR-10 Raspberry Pi Integration

thingiverse

I integrated a Raspberry Pi inside of the CR-10 electronics case. Instructions: * Cut a 54mm x 20mm hole 11mm from the top and 40mm from the back of the case. * Epoxy Pi mount in place. It should be 20mm from the side wall where the hole is cut and about 38mm from the back inner wall. Tip: Attach the Pi to the mount, then epoxy the mount, making sure everything is properly aligned. The additional weight will help hold the mount in place while the epoxy dries. * Epoxy the IO cover to the outside of the case. The top of the cover should be 9mm from the top of the case and 32mm from the back of the case. Tip: Position this with the Pi in place for easier alignment. In addition to the Raspberry Pi mount, there's a single channel relay and a LM2596 DC-DC adapter with spacers to mount above the Raspberry Pi. The Pi is powered by the 12V power supply using the LM2596 and the relay to toggle power to the CR-10 main board. The rear exhaust fan was replaced with a quieter one, rewired to run independently of the main board as long as the power supply is on. The front fan still powers on with the main board. Note: If you just want to integrate the Raspberry Pi and power it independently from the power supply cable, put it through the existing cable grommet. Note: The Raspberry Pi is placed directly over the cable tie mount. The mount will still be usable after installation; wires will just have to run under the Pi.

To mount the new fan, I used some M3x12mm screws I had around.
