My DC21 motorized head brushbar motor stopped working. It turned out the center gear inside my DC21 motor head brushbar motor was completely stripped. Dyson doesn't sell or fix these anymore and recommended I buy a whole new Dyson vacuum. Using the broken part and some trial and error I came up with this replacement gear. I made my first replacement, printed with PLA, over 3.5 years ago and it just failed last week. PLA is not ideal for this use case but it is currently all I print.
I printed this with 0.1mm layer height due to the diagonal teeth and 3 walls for strength. Fill percentage doesn't matter much. Support is absolutely required.
I thoroughly cleaned the motor gearbox and packed it with white lithium grease during reassembly.
