Printable Trumpet

http://www.thingiverse.com/thing:772936 is a better version of this trumpet if you're interested in building one.
This is a 17 piece printable trumpet. It was modeled somewhat after a Bach Stradivarius. I have printed one myself and the sound quality and playability is honestly pretty bad. The reason I am posting my files is so people can try their hand at improving the design and to print it for themselves.

It takes a while to make this. Almost all the parts require post printing work and some require a lot of it. Probably 5ish days of just printing time.
Here is a video of me attempting to play it. https://www.youtube.com/watch?v=B1j_d2mSGng.
As I said, it doesn't play well at all.
If you have any design questions or need help please message me.
Edit (4/15/15) I uploaded the new version as a remix here. It's the same thing that was in the dropbox that I sent to some people earlier.
Edit (3/8/15) I have redesigned everything and started printing a new trumpet. The new version will be much more printer friendly (all the pieces will be under 5.5 inches) and I am fairly confident It will have a significantly better sound.
New parts added 2/8/15 Check instructions for details.
