Finally built myself a nice 3D printer enclosure from IKEA cabinets.
Basic idea is to take a shallow (20cm) and a deep (40cm) cabinet frames and to stagger the bottom/top panels and wall panels, making a nice single-piece 60cm cube. A bit more info with a short how-to and a few ideas and nuances.
Oh man, one of my white whales is getting one of those sturdy old media centers and turning the whole thing into a combined printer/cnc/laser with attached console and storage. Huge build area, head swapping, and all the gear you could ever need in a gaudy wall of wood grain and brass fixtures.
