Drive gears I tried to replicate for my Alpina AL4 lawnmower, as both factory gear teeth are worn out and I haven't found anywhere to buy them. These are not exact replicas, as they were measured with a caliper, but they get the job done, at least for some time. Requires further testing. Printed mine in PETG, but I'm unsure how long they are going to last. Printed with 6 wall loops, 50% infill, 0.20 resolution, with supports, although untested and you may adjust it better.
