I use mine largely for TTRPG stuff, but it's the little things that are really satisfying. Like throwing together a little bracket that needs to be exactly this shape, and then being able to test fit it, make adjustments, and print up the exact perfect thing that no one makes for the exact purpose you need it for.
I'd like to get a 3D printer but I live in a 1br apartment so I don't have a great place to put it. I might be able to make space in the living room or bedroom but I'm a little leery of health concerns (seems like a bad idea to have something that's melting plastic right where I'm sleeping or eating, is rather have it in a garage or basement or something)
