Parametric Music Box

CUSTOMIZER CHALLENGE CONTEST WINNER - Artistic Category
This is a 100% printed customizable music box!
Only 3D printed parts are used in the design and it can be assembled and disassembled via printed snapping mechanisms.
The project originated when a friend of mine said that he'd only be interested in 3D printing once he can print a music box ;)

I'll try to keep the .scad file on this page updated but to help me to manage the design and to make it easier for others to contribute: https://github.com/wizard23/ParametrizedMusicBox

<b>Case:</b> the large thin walled part that holds the vibrating teeth and holds everything together
<b>Music Cylinder:</b> the large cylinder with the pins (that encode the music) sticking out
<b>Transmission gear:</b> sits between the crank gear and the music cylinder
<b>Crank gear:</b> drives everything, connects to crank (insert it through the round hole in the case)
<b>Crank:</b> for manually driving the box, connects to crank gear and crank pulley
<b>Pulley: </b>for holding the crank while turning it
With the default parameters you get a complete building plate that can play one full octave range (13 half notes from C to C) in a medium footprint that should fit in most printers. You can enable each part individually to make smaller print plates.
