Gear for the odometer in a classic Volkswagen Beetle (my '73 model, don't know about other years or if it might be useful for other models) that commonly breaks and are hard to find replacements for. Others might find this useful. Can't remember my print specs, I believe I printed this with a 0.4mm nozzle. Glue onto shaft with superglue. Has held up for numerous years and tens of thousands of miles.
