The wheels on my suitcase fell apart on my last business trip. I am too frugal to toss it and buy a new one. All you need is a pair of calipers, a CAD program and a 3D printer. I drilled out the riveted shafts and removed the old wheels. Then I designed a new wheel and printed 2 in PETG. I used 1/4"-20 carriage bolts and nuts for the shafts. Rolls smooth now. As an added bonus, my blue suitcase with green wheels will be easy to spot at baggage claim.
