DISASSEMBLY / ASSEMBLY:
This drone flute arrives assembled in numbered pieces. Please disassemble with care if deciding to do-so for portability (slowly wiggle around the joints as you pull). When re-assembling, please follow the numbering sequence. We recommend connecting the pieces part-way by hand, and then finding a hard floor surface (either with a rug or carpet) to tap the rest of the pieces in place until they lock (rubber mallet works great as well if needed). We designed it this way to ensure the airways remain tightly sealed.

Real customer stories
Great flutes. Wish the ads that claim they're only $30 would be updated. You can't get a good one for less than $60.
I have to admit I was a little hesitant but really wanted to support a company that was using 3D printing to make something interactive, fun, practical and generally making music a little more accessible for folks who want to experiment with new sounds without investing a huge amount of money. I was pleasantly surprised at the sound quality and the ease of playing. Getting the breath right takes a little practice but it's a wonderful addition to our collection. I also appreciate that it breaks down easily so it can be cleaned and also packed for travel.
Thank you so much for this thoughtful feedback! We’re glad the instrument exceeded your expectations and that you’re enjoying both the sound and playability. It means a lot to us that you value the accessibility, portability, and care that went into the design. Happy playing!
