Movable Mass Balancing Toy

Inspired by the Disney Research paper on balancing toys with movable masses I created my own L-pipe toy to experiment with the technique. The STL has a pocket for a 16mm diameter marble The print must be paused between 27mm and 30mm for insertion of the marble.

Update: I uploaded the wrong STL version initially. That has been corrected. as of Oct. 10 2016.
