New parts for my motorcycle are not made anymore, and used are getting harder to find. The choke lever broke off and I needed a replacement, designing and printing one took only an hour or two. I placed the broken pieces on a scanner along with a card for dimensions, scaled and made a sketch off of it in fusion 360, the rest of the dimensions I got with calipers. I printed extremely rough with a large nozzle at 0.3 layer height in PLA as a prototype, but It has been on my bike for 2 years and still works.
