Customizable pull string top

thingiverse

Create a fully customizable pull-string toy top by adjusting its shape and size for optimum speed and distance. To enhance mass, print it using high infill; however, experimentation with various infills can be enjoyable too. Print the file in one go but split it using software like netfabb to separate the top and launcher. Glue the handle into the top, slot it into the launcher, thread a string through the hole, wind it up and pull! Have fun exploring different designs, but note that any poor results are your responsibility.
