I’ve found the perfect enclosure for my Prusa i3 MK3 3D printer (no modification needed!). It’s a cheap server wall mount cabinet for only 79,- EUR. You can find it on ebay or in different computer online shops. It has 4 mm safety glass and powder coated sheet metal walls. The roof and bottom have cable entries and the roof is also prepared for mounting 2 x single fans. That may come in handy if you want to build a fume exhaust for ABS printing.

This cabinet is available in different sizes and colors. But you need the biggest one (with 15 Height Units and 600mm depth) and the Prusa i3 will fit perfectly. Also the heat bed cable on the backside of the i3 has enough space without touching the enclosure, no modification needed. Since this thing was meant to be mounted on a wall it’s baseplate is not that sturdy. Don’t use rubber feet directly on the bottom side of the enclosure it will be too wobbly! Instead screw a thick plywood board to the bottom side to give the enclosure more stability. On that plywoodboard you can now fix some rubber feet to it if you want to use it on your desk.
