Before I begin here's a little information about myself:
I am a student in Israel Ra'anana at the age of 15. I use Inventor and Cura to design and print. I've been into designing for about a year now and I now do it as a class in school 2 years ahead of time. I am rather new to the printing part and you can see it did not print as perfect as I'd want it to be.
A tune box (music box) I designed & Printed, it consists of 3 parts:
The wheel is divided into 8 sections in which one is missing in order to Play the music right.
On the base are mounted 3 stripes at the thickness of 2, 3 and 4 mm, with each plaing a diffarent note.
Connecting the handle is done with friction using an extending hexagon on the handle and an inword going hexagon (slightly larger) in the wheel itself.
Although the original device is made on metal, building it out of pure platic did produce a sound, yet not as "clean".
The base and the wheel both have a hole in them so it is easy and clear how to put it together :)
