I, too, am designing an enclosure for my printer, as it's getting relocated to the basement. I don't have any materials yet, just the plans. It'll be made out of 3/4 inch plywood, all the electronics mounted on the outside, with a RaspberryPi for printer control, camera and web access.printerbox4.jpgprinterbox2.jpg
The printer will be mounted to a square of plywood which can slide in and out of the box for maintenance. Lights and a webcam will be on the inside so prints can be monitored without needing to open the box. Internal dimensions will be 2ft cubed, plus a little extra in the Z to accommodate the printer shelf. I intend to have some flexible tubing connecting to the rear of the box and to the hotend fan to prevent overheat jams.
