Yamaha Baby Grand Piano Timbre Modifier

This was my final project for Rhino 3D Modeling class in college, and I had to upload the files to Thingiverse as part of the requirements.
It does not work very well.
The red parts are 3D printed (Makerbot Replicator 1) and the beams that connect the two red parts are laser cut plywood. It requires specific nuts and bolts, and I unfortunately do not have the dimensions down. In order for this to be used, it requires modification.
