As someone who bikes to campus almost every day, I was in trouble when I realized I lost the cap to my bike pump. The cap makes the whole pump work, so I was looking into replacement options. Luckily, other people had faced this same issue. Rather than buy a new pump, my friend found an .stl file for a replacement! We had to print in tiny layers, but the threading worked and the cap has been successfully replaced. Everyone in the Design Lab was delightfully helpful and we decided to make a few of them in case some were imprecise. Now I've even got some spares in case this one falls off. Thanks to the Shapiro Design Lab for letting me keep this pump in use
