Who knew you could 3D Print a Trombone?!?!?! When I found out my Shires Q30 Axial Valve trombone was modular, I knew I had to make an orange bell. The bell prints in 3 separate pieces, and there are 2 screw attachments also. All 3 pieces can be superglued together, and so can the attachment pieces. It actually sounds far better than I thought It would!! Certainly not as good sounding as the shires bell, but it looks WAY better when it is your favorite color!
