Window Track Wheel

thingiverse

Several windows in my house have been stubbornly resistant to opening and closing, but I've managed to resolve this issue by targeting the culprit: flat spots on the wheels within the window tracks. To repair these wheels, I first printed out replacement parts without relying on supports. As soon as they were ready, I snapped off and discarded the two lower rings at the base of each wheel, allowing it to snap directly into place within the corresponding track located at the bottom of the window.
