3 Oz. Disposable plastic cup dispenser

This is a cup dispenser intended to hang on the wall above my wife's vanity in the bathroom.  It's modeled to fit the 3oz. plastic cups from Walmart, but I'm sure it could be easily adjusted to fit others.

I included a test piece that should be printed first.  If the test piece fits whatever cups you'd like to hang, then print the dispenser and lid.  Otherwise, scale the test piece up or down and retest the fit.  Apply whatever scale factor works to fit the test piece to the cups to the lid and dispenser and print at that scale.
