Just messing around with my printer last night and printed a few 40mm edf fans that are designed for a Emax 1106. Any chance these won’t explode on 4500kv 4s?
i would recommend wearing goggles and to keep all small children and pets out of the room when you spin those up. sorry but they are gonna self-destruct.
I’m expecting them to pop. And yes I’m spinning them up tonight. I put them on a little mandrel and spun them at 13000rpm and they looked straight, and smooth. But that’s a far cry from 60,000-65,000rpm depending on how much power they draw.
Your quality control factor must be very reliable if you’re willing to spin them up holding them in bare hand. Amazing what 3D printers can do. They’re getting cheaper & small enough to use on a limited space hobby bench.

I also have a machining center with a 4th axis at the shop. I’ve been thinking of just milling some fans, and housings. I even have some magnesium I could use. Then I cone to my senses and just buy a $35 unit. 🙃
