I have build an enclosure for my Creality Ender 3 Pro inside a IKEA Stuva cupboard. Unfortunately the Stuva line is a little to small to comfortably fit the heat bed cable together with a cable chain so I made a hole in the back of the cupboard and printed a fitting cutout to get more room.

The hole in the back panel of the Stuva cupboard should be 56mm wide and 164mm tall.
