Set of Gears

So I have no idea why anyone would actually need these. But there is a neat little story behind them and I am proud of the pieces so I'll go ahead and share them.

At my school, apparently a really old paper towel dispenser gave out. The old gears had shredded and they needed new ones or they would have to tear the old ones out of the wall (about $1000 or something like that). The only way to avoid that would be to have the parts printed. So they gave me these shredded gears.

Not having much experience with sketchup or any other programs, I used tinkercad to create these items. It took me about 12 hours of work with a caliper to get this all done. And the pieces worked! A $1000 repair done for $5 on a 3D printer.
