Ring in the New Year and entertain your friends with the soothing whimsical sound of a dentist's drill run amok. This printable siren whistle and noise maker is inspired by a classic cereal box prize, and it works like a charm.

Drop the fan onto the post with the side that was on the build plate facing up. Make sure it spins freely before pressing the lid on. A gentle tap with a soft mallet helps when seating the lid.

For best results, we recommend the following settings.

Note: use ABS for the whistle and fan, and PLA or ABS for the lid.

Infill: 10%
Layer Height: 200-250 microns (0.20-0.25 mm)
Shells: 0

made with printrbot, had to use very slow setting for impeller on first few layers to keep it from popping off

Anonymous - in reply to

works great, vibrates a little bit but still satisfying to play with

Made one entirely out of PLA and it still makes a suitably whizzy noise! Thanks!

Looks good... prints not so good.. works not

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?)

That is correct; there always needs to be at least one shell. The number in ReplicatorG denotes the amount of "extra" shells on top of that 1, while the MakerWare figure is the total shells including the first 1.

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?
