Are you sweating over a pile of messy wheels, struggling to find four identical ones after searching for ages?
This little gadget can solve the problem. Print it in one go—no supports needed—and just use a 3mm zip tie (if you don’t have one, I’ve also included a dummy zip tie in the design, though it may not be as flexible or practical as a real one).
Once the wheels are attached, the center of gravity of the entire hanger stays perfectly balanced, so it won’t tilt awkwardly on the wall—a dream come true for perfectionists!!

Replace the hex nut with a hand-tightened knurled nut
