After the scaled down version(see my designs), here is the real thing. A full sized trumpet. Dimensions are modeled from my 50+ years old Selmer which sounds very good. Placement of the 3rd valve slide is altered for simplification purposes. Includes a monette style mouthpiece. Also can be used with a standard trumpet mouthpiece. Valves work and valve routes are modeled realistically This should produce sounds. All valve slides move in addition to bellbow and main tuning slide to tune the instrument in case it is out of tune. Modeling time 4 days. Comments are welcome. http://www.youtube.com/watch?v=rt6cvjgmH2s I've printed the mouthpiece part to test. This is the first trial with the unsanded rough piece, right out of 3d printer. http://www.youtube.com/watch?v=PNcpmNXEF3M see it being played by a non trumpet player, not bad https://www.youtube.com/watch?v=WkAavq1R1P0
