makerware 2.0, makerbot replicator 2, "anything" i try to print at 0 shells just beeps that its done before i even start. i have to add at least 1 for it to print. I assume we mean 0 "extra" shells? (or maybe everyone knows this and im just dumb?)

Built the lot out of ABS all with default settings and worked great

Printed all the parts but the post the fan goes on is either too thick or i need to adjust the resolution, i couldnt get the fan to spin. very good design though. i will try again after i fix some things.

I printed it with pure hope. But it didn't give any noise , except my breath...:)

0 shells? I assume that doesn't mean what I think it does, perimeters...?

Prints well in ABS with PLA raft. Total print time at 1,5 speed in High res (0,125mm) is 4:29u. Body parts fit like a gloove. Printed on a two-head BFB 3D Touch, fill density 50%. The turbine shaft is slightly loose. Reducing the tolerance with some tape improved the revving so a tighter axle-fit might make it an even better whistle. There's a nice sirene effect using lungs so a 1,5 bar air-pressure is effective enough at least with this print. A 50% copy still works well but does not produce a whistle-sound untill a little refourbishment is done. A PLA print might be more precise and effective. Unfortunelately the Makerbot logo catches the eye immediately and grinding is not an option!;-)

I very much liked this print, Chris.

Mine sounds exactly like thecrazy's.  The parts fit well together and the fan rotates freely, but the rattle is all I get.  Like Mythbusters, I had go to extremes so I hooked it up to my air compressor at the lowest stable pressure I could get (50psi and about 6cfm).  I could get a whir that sounded more like a dentist drill.  At 70 psi, the whole thing split apart.

I dont know about you guys but this thing doesnt whistle so much as it rattles. Quite deceiving actualy. Dont know if its cause I printed it all out of PLA but i dont see why it would make a huge difference. The fan is quite loose inside though.

The sound description is "dead nuts" on.  Sounds like a dentists drill with a wobbly bit drilling into teeth.  Very unpleasant :D

The "WHISTLE FAN" - its getting flagged as non-manifold - there are tiny holes on the bottom layer where the blades come together.  
Not a big deal for printing but when I tried to plate them together in OpenScad it complained. 

Looks like WHISTLE x 1.STL may be wrong?
