About this 3D model
This uses your Z stepper motor as a speaker, and plays the Imperial March. Print the g-code file. Enjoy. This originated from Makerbot (Ugh) https://www.youtube.com/watch?v=DzDZLwaDzys There is a python script here: https://sourceforge.net/p/reprap/code/HEAD/tree/trunk/users/metalab/python/MakerTunes/ The STL file is junk, and only included to satisfy the thingiverse thing upload requirements.
