A friend down the street broke a part off of the outboard motor on his fishing boat. I would call the deadman's switch assembly. He referred to it as the lanyard clip. Whatever the actual name is, he couldn't find a replacement part.

3D printer to the rescue!

A few caliper measurements, CAD work, slight tweaks for supportless printing, and 15 mins on the 3D printer and the boat is back in action!
