I created a replacement Tool drawer for the CR-10 Smart that house a Raspberry Pi running octoprint. The drawer has mounts inside for the Raspberry Pi and honeycomb bottom for venting. There is a opening in the front of the draw so you can run a USB camera connection out. To use this drawer setup you will need to open up your CR-10 Smart and cut out a hole from the drawer area to run the cables internally. You can see how I did this on my youtube video here... https://youtu.be/_MaLafO6DYw
