Bank Bottom Plug Stopper

The bottom stopper/plug for a bank I have was missing. Modeled this up and it fit perfectly. The bottom hole in the bank was 1.25" diameter. Once printed, you will need to file/cut the two ridges closest to the bottom circle, in order to allow the plug to "lock" into the track. I was going to model this in, but the thickness was so thin on my bank, I didn't think it would make it through the 3d printing process.
