Drone Whistles?

I recently purchased a little 3D printed drone “flute” that is in D major and have been having a lot of fun with it. I find the sounds that I can make with it fascinating. I know that I could probably tape a couple of Generations together and block off all the sound holes on one but I’m looking for something a bit more permanent. I see that Carbony makes some but they are way beyond my budget. Does anyone else make something like this in metal or a heavy plastic?

Thanks!

This might be exactly what you purchased, but there’s a guy on Etsy who 3D prints these: https://www.etsy.com/search?q=teletunes&ref=search_bar

No idea if they’re any good. But Cedar Dobson likes playing them.

That’s probably the guy who made the one the OP has. But beware, that extendable low D one Teletunes offers is completely unplayable. I find it baffling it has any positive reviews at all. I paid like $15 for it and i felt like an absolute sucker

Yes, it is from Teletunes. It isn’t the extendable type. I have ordered one in C and a different type in C as well. They sound pretty good for how much they cost. As one would expect, they seem a little “delicate”.
