I had no idea what this was for when I uploaded it. I didn't think it would be useful for anything other than as a 3D print demo, I just made it to satisfy my curiosity. But if you check out comments below, guttyr discovered you can spin it up by blowing on it, and it can be used by speech therapists to help special needs kids get better at breath support and control.

Different parts of the spinner will spin depending where you blow on it, I'm still figuring which locations and angles work best. Maybe it'll help me too as I'm frequently out of breath when I'm at altitude or underwater.

It can be printed with a 0.5mm extrusion width and 2 perimeters without infill.

Printed in Atomic Filament Granite Grey PLA and Octave Precision Gold PLA*

Are there individual pieces that you can post? I want to try to make a big one with more layers.

It would be cool if you could make it so that they satay together better, thanks!

I must say it is a cool design but your print quality is absolutely amazing. I cannot come close to that quality even at .1mm later height. I would love to know the name of your printer please.

What kind of printer do you have right now then?
I can easely get this quality and better on my Felix 3.1.

I have a flyingbear p902 from China. It has good specs and I built it myself so I know everything is good structurally. It does only go up to 50microns but it is a full metal construction like yours. I am guessing you have better settings on your printer because I havent messed with it much after I got an ok result with the prints

Yours looks alright but not super sturdy witch may cause some wobble. And you just can expect to get the same results from a 400$ printer than you get with a 1500$ one. But messing around with print settings should help you get a long way. I always just print something small and simple again and again while everytime changing something. And i just stick the prints on a piece of paper with the changes in the settings under it. The Print Quality Troubleshooting Guide from simplify 3D has very usefull info for a lot of problems.

what 3D design software do you use

How about a version with a stand on it?

Hiya Walter.

Just wanted to let you know that these are being used by speech therapists helping special needs kids aged birth to three get better at breath support and control. Because your design spins so well, a directed "whoosh" of air is enough to get it going. The therapists and kids both love 'em!

Thanks for creating and sharing this design!

Wow that's really incredible! Thanks for sharing that, it's really cool to hear! Ironically, I had this thing tagged as "useless", I'm glad to see someone prove me wrong in such a spectacular fashion.

Wow, i just gave it a try, I had no idea it could be spun up that way, now I'm out of breath :)

This is the best bearingless spinner I've ever messed with. Great design!

does this need support?

nope prints flat

pretty cool this is pretty fun to fidget with
what was this modeled in?
