I made this a few months ago for a Wikipedia article. It's supposed to instruct how to remove a snap-ring from a rear bicycle hub, enabling removal of the sprocket. I had a lot of trouble working out how to remove it from my bicycle and so I wanted to save other people the trouble (I tried to get a well-known webmaster to put it onto his famous-within-the-online-cycling-world website, since he advised me on what to do but unfortunately he passed away a short while after I made it).
It took me quite some time and I did it
before I'd found the extrude tool!
