I recently picked up a 1964 Midway Space Gun game and it turns out that a plastic sprocket that drives the main target wheel is damaged beyond repair.
Basically looks like years of use has sheared off the sharp edge that held the sprocket to the key on the end of the shaft that spins the target wheel.
Finding a replacement is probably beyond a needle in a haystack, so I was wondering if I could get a replacement sprocket 3D printed. Was hoping to find a place that could use the original sprocket as a base as I have no experience making the 3D digital files. One key is it would have to be made out of fairly tough plastic as it is connected to a bicycle chain.
Any experience or recommendations? Thanks!
