This is rather specific but maybe someone else can use. My new Bissell 3194 Little Green Pro cleaner came with two brushes but nowhere to store the 2nd one. I know myself and knew I would lose it quickly, so I fired up TinkerCAD and whipped up a holder to hang off the side. Works well!
Printed at .3mm with “supports on build plate only” - Prusament Gentlemen's Gray was a good match.
Made the tinkercad model public and linked below if anyone wants to mod.
