Update 2016-10-21: I revised this to make the hole slightly smaller, as it was too large to fit on the screws from my boxes.
I wasn't happy with the prints that I got from using the original STL, so I re-drafted this in OnShape very quickly.
I break these things regularly, and got tired of paying $0.50 to replace them.
