3D-printed flutes hit new notes | Researchers have found a way to 3D print instruments that produce notes unattainable through traditional instruments.
Hand-crafted instruments are all well and good, but the precision of 3D printing is starting to unlock new sounds.
Leading a team of researchers from the University of Wollongong in Australia, Dr Terumi Narushima took the existing mathematical models used to determine how various notes are produced by wind instruments, and created a 3D model of a flute that – due to its customised diameter, length, and hole placement – produced unique microtonal notes smaller than a semitone.

I wonder if they missed a big opportunity with 3D printing? Recorder finger holes are round because that's what you get with a normal drill[1]. Maybe there are some advantages to square or rectangular (or other shape) for the finger holes?
Proportional hydraulic spool valves have rectangular holes that are uncovered by a piston (the spool) -- piston motion translates (nearly) directly into valve open area.
[1] There are special "drills" that can make triangular, rectangular and other polygon shaped holes, here's one type,
