Native American Flute - low D

I scaled the original F# tuned flute to D, and had to modify the parts to make it fit into Bambu Lab. The flute works and sounds great! As far as my severy lacking skills can measure the pitch, it's perfectly in tune (A = 440Hz). The sound is beautifully deep and soothing with some nicely complex overtones. Sound sample (beginner):

As the scaling made the sidewalls thicker as well, I also made a version with slightly thinner walls (4mm vs 5mm). Internally they are identical.

For the thicker version there are both the original straight top part as well as a redesigned one with an angled mouthpiece. The thin version only has the angled part. Internally they are all identical.

All the mentioned versions are included, as well as a .3mf file for a ~6hr print on a Bambu Lab.
