A friend gave me this Prusa MK3S+ a few years ago and it came inside a set of Besta storage cabinets, 2x 40cm deep ones. Its was always a bit unwieldy in my small apartment and since it was on the ground, I have to always bend down to do anything.
I'd been searching for decent options for a while and it seemed like the cabinet I really wanted was only available at IKEA USA. I'm in Canada so I decided to get a bit creative.
This cabinet is 60cm deep and 2 units tall. I joined a 20cm and 40cm Besta for both levels, but offset the joint. Top is 20+40, bottom is 40+20 (when looking from the front). That really helped with rigidity and then adding some plates across joints at top and bottom.
The side vents to the window, which, if I'd measured right the first time would have been 1 hole instead of 2, but its not visible so, meh.
I'm incredibly happy with how this turned out. My next step is a rubber pad to sit the printer on and then adding so of the vehicle sounds dampener to it as I've seen someone else do. Though, truthfully, even the cut up yoga mat under it has made a massive difference.
This looks so much better and easier than half-assing LACK tables and plywood/plexiglass together.
LACK was an amazing option back when they were $5 a pop though. I built my Ender 3 cabinet for like $30 total by getting four lack tables, an Ikea picture frame for the door, and EPA floor mats for walls. Four, because the filament used for printing the leg extensions would have cost more than the tables put together so I just cut them from a sacrificial table.
It's no beauty queen, but has worked fine for years now.
Today, the tables alone would be $65.
