Kohler toliet seat fitting clip quick release

thingiverse

I'm not sure about the part number on that Kohler toilet seat clip - it's a little mysterious, but I think it might be related to quick-release hinges. If you happen to know the correct part number, please do share. If you were to create one of these clips, I'd love to hear the story behind how you managed to find or recreate this replacement. What happened to the original clip? How did you come up with the design for a new one?
