Cigarette pan-flutes (smoking alternative)

Pitch:
Is your friend, coworker, or family member smoking?
Would you like them to stop?
It's easy! Just replace their smokes with these revolutionary therapy props.
They will totally not hate you!

Why did I do this?:
No seriously, I made these as part of a challenge to help my friend stop smoking. I told him that if they stopped smoking for a weekend I would make and print something unique for him.
He followed through and I gave him the first version, then kept upping the challenge and made more.
We also pranked other friends with them, which I highly recommend!

Design details:
I designed them to be fairly tuned to a certain note depending on the length.
7 notes with good sound: B5-A6, 2 that are questionable.
I also made a little mount to create a 7-flute pan-flute.

Print hints:
I print these on my Prusa MK3S+ with a 0.25nozzle since it creates a better sound for some reason.
I split them at height 20mm to change filament and print them one by one with brim.

Enjoy!
