Since 3d printers are on the rise and getting cheaper, I've been looking into them, and I had a great idea. Since vacuum parts can be pretty expensive, why not make your own? For example, my Hoover 28's original hood has a noticeable crack in it. If I made a replica, I wouldn't have to worry about accidentally slamming the vacuum into some furniture and ruining the vacuum's original parts. Maybe you could make your own brushroll(although you would still need to add the bristles).
