Replacement gear for Noritsu lab film development machine. Don't know what it's called the one at the local development lab broke and I printed a replacement years ago at high infill PETG, and it seems to work.
I'm pretty sure it's for a Noritsu V50 in the US, but I make no guarantees. It's similar to the gear in the picture but I'm not 100% sure that's exactly the same dimensions as I'm not sure what the part is actually called.
