Summary

Just in case someone was crazy enough to try and print this I broke the original flute apart and uploaded as a STP file.

The far left main flue body is modified by me to remove the rods for finger keys since they cannot be assembled if using the original design. I added holes so someone could try and remodel the flute with the finger keys and removable rods. Note there is a special rod on far left.

The middle main flute body is unmodified but deconstructed.

The right main flute is as designed.

The green pieces I am assuming need to be rubber material or similar. Same with the blue key seals.

The red piece is a part that needs to either be heavily repaired or remodeled because there are some bad faces and missing edges.

If this was really going to be printed by someone some significant work will need to be done to deal with tolerances (even on a SLS printer).

The main flute body without mouth piece is 492.43mm long.

I included a STL of the modified main flute body because thingiverse requires one STL. Really though modifications need to be done with something that supports STP so I am not including the other parts as STL files.
