Music Box Cylinder
by failrate, published
Description
The result is a reasonably typical music box cylinder with adjustable tooth and braille count. This version is probably not well formed for MakerBots, but could be sintered. I have an idea for a MakerBot version, but it's running late ;)
todo:
- Accompanying worm gear (or spring, clutch, drive gear assembly?)
- Comb
- Base/Box

I have no way to test it yet, but would abs or pla being plucked vibrate enough to make sound if it was attched to a resonator box? possibly something shaped like a square spiralled car horn?
It'd probably make sense to find an existing mass-manufactured music box that we can just replace the cylinder on, rather then reinventing that particular wheel? (On the other hand, if we go the custom route, we can make combs that have exactly the notes we want.)
Also, making a makerbottable form of this would require only that instead of having straight-edged cylinders sticking out of the drum, you instead had the edge of a disc poking out. The disc's edge would jut out such that it can be printed as an overhang of less than 60%, which is easily makerbottable. The widening of individual notes/notches caused by using disc edges can be accounted for in the choice/design of the comb used.

@Erik My immediate notion was the same!
If we can get a cheap metal tooth-harp design up on shapeways, then the rest of the music device could be makerbottable. Once there's a script to convert music (perhaps MIDI format music, also?) into a drum, you've got printable music!
Was actually about to look into the possibility last night while playing with a little music box (Sound of Silence). Failrate, you read my mind! :D
