About this 3D model
There are enough mouthpieces on Thingiverse so I wanted to create the whole trumpet. I modeled it off of my own Back Strad dimensions. The only missing components are the valves which are very tricky to CAD. If there is legitimate interest in building it then I will work harder on the valves, and make sure everything is printable on a home 3D printer (as it stands, not all components fit). This was more of a "see if I can CAD a trumpet" experiment. Definitely a work in progress. And happy upload the .sldprt/.sldasm files if people want to work on it.
