Our house has a daylight basement that’s set up as a separate living area, with its own entrance. Up until last January, our daughter and SIL lived down there, and our granddaughter had a bedroom upstairs. When their second child was born there wasn’t another bedroom available, so they converted a large closet in the downstairs family room into a tiny nursery. My SIL installed a vent that tied into the bathroom vent, so he could put a standalone A/C unit in the “nursery” to control the temp and circulate air.
When they moved out, the downstairs family room became my craft area, and the former “nursery” with its ready-to-use vent system turned out to be a perfect place for my Glowforge, which arrived in February.
I went to Ikea and got some kitchen cabinets to use for drawers, and found a really heavy / sturdy countertop in their discount area that someone had custom ordered and then not purchased. When I got it home, it turned out to be 1/4" too wide to fit into the space. I didn’t have any good way to trim it, so I decided to just cut a hole in the drywall to make it fit. (My husband thought this was a hysterically funny solution. I thought it was completely practical!)
The hole I cut was a tight fit, and the space isn’t totally square, so I ended up having to do a lot of shoving and pounding to get the countertop installed, and then I had to do some touch-up painting. But I got it in there, and managed to get it perfectly level. The end result is a SUPER solid, flat surface that is pretty much completely bump and vibration-proof!
