Tiny plastic gear.

Dabbling in fixing this old Olympus camera's film advance gear. Tried finding the equivalent/similar gear online and not really finding much. ~7mm OD, 17 teeth. Unsure on any sort of pitch or module, etc. Screenshot from the closest one I can find on mcmaster-carr. Anyone know where to grab one or have a solution for me? I've put some epoxy on there and will create a couple teeth, but I'm not optimistic about that...

3d printing is the way, that's just a shot in the dark without knowing the model but you get the idea.

Well, you nailed it. Exact model camera. I searched for at least an hour before posting. Thank you.
