Pipe Organ Reed Pipe

Was bored some time ago and had the idea to challenge myself to make a 3d printable reed pipe with different resonators. The tongue has to be made out of a thin sheet of metal, preferably brass, but I used zinc, because i had a small piece of it laying around. This piece of metal must be slighty curved, as you can see in two of the pictures. The curve shouldn't be bend too much or too less, because the pipe won't speak correctly. The tongue is secured by a M3 screw. To hold the resonators on top of the pipe I just used some tape.
