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.
The one in the picture does not have ventilation, I even said
Just needs an exhaust.
Which is what I am putting in next :)
However, I did a small ABS print, could not smell it outside the cabinet, and when I left it to cool for an hour, the smell dissipated somehow. I'm still putting an exhaust in though.
