Multi Color Tennis Racket

There is a tennis racket key Fob on Thingiverse that was while very pretty left a lot to be desired. The main issues I had with it that it was obviously not designed with a 3d printer in mind and it was made by more of an artist than an engineer.

The main issues I found with it were that it was not a true two color object, the string dimensions were horrible that caused it to be impossible printing with a normal 0.4mm nozzle with 0.48mm width (I mean who sets the string dimension to 0.39 mm?)
