I put together a new bike and noticed that one of the rubber plugs for the M5 fender mount was missing. Rather than trying to get the LBS to give me another I decided to model up a replacement. Unlike the rubber plugs this has M5 threads so it will have to be printed at 0.10 or better layer height to get half way decent threads to print.

I figured I'd put it up here in case anyone else is in the same position.
