Sphero Halloween Costume

Please watch http://youtu.be/EARzoE6KvSg for running scene of this thing.
I successfully print the parts with Bukito 3D printer, but you might need to file the latches for fitting.
There are four identical parts for the wheels, but actually these are 2 pairs. Please glue each pair together. Also you might need to adjust the smoothness of the axis and axis hole with a file and a drill, etc.
The black cap/hat is glued.
Good luck and have a happy Halloween.
