My printer is in my office. I wanted to have it on a mobile cart so that I could easily move it to another location while it's running. This is partially to limit the noise while I'm working, and also because by my family is sensitive to PLA printing so it's nice to be able to move the printer to an unused area of the house. The casters of the Ikea BROR utility cart have a little wiggle to them while printing, so I created some wheel locks to firm everything up.
