Could you design a Housing for it? And btw awesome Thing! I printed 2 of them at the same Time and they turnt out great! But i thought they would be bigger. The next one will be 200 or 400% Scale :DD

Could anyone say something about stability if i scale this by factor 3,75 to get a diameter of 15cm. The inner hole would then fit a 10mm shaft. The fan would rotate with speeds of 12000 to 14000rpm and would be used in an rc helicopter.

would it be possible to convert it into a form with a ring in the middle, to fit on an ordinary small computer fan which has all extras cut off? something along the lines of http://www.thingiverse.com/thing:186979?http://www.thingiverse.com/thi...

Cooling fan replacement blades

Thanks for making a solid bottom version available... Although I was able to get the raft off.. it took quite a while... I suspect that the slight decrease in efficiency will be more than compensated by the easier production...


How did you calculate the curvature?

Is it optimized for airflow at a specific speed or something?

To be honest, I just made it up as I went. However, it works well though. As noted, this is a work in progress and I will be making variations and revisions as I go.
