<VV> My new experimental fan

[Jay Maechtlen]

Well- if printed in a plastic, I suspect it would need thicker sections 
for mechanical strength.
After all, it is not just going around, it is pushing lots of air!
And the accel/decel of the fan (rapid change of rotational velocity) 
might put some interesting stresses on it.
But the curve of the blades may make it very strong against change of 
rotational speed.
