The IKEA milk frother is ridiculously cheap. A nice little electric motor with battery compartment, switch and shaft. I just had to use it for something sensible. Print, assemble, turn on and enjoy the cool!
There are five fans in the main image. The bottom left two are the ones I recommend, if in doubt try the five bladed fan. The others are variants except top right which was an unsuccessful attempt at using thing:4941. Despite other fancy propellers I decided to go for simplicity and ease of printing. Which doesn't apply if you go below 45 degrees for the fan blades.
It does tend to wobble a bit, it spins faster if you hold it loosely (which I find kind of strange).
My next projects with this may be to use it for propulsion for both wheeled and aquatic toys!
NOTE: Despite the name I am NOT a fan of IKEA! :-)
NOTE 2: If only thingiverse wouldn't crop thumbnails you could actually see a thumb of the milk frother.


The scad file is pretty parametric, go nuts!
I've provided stls for a three and five bladed fan.
Buy a milk frother or twenty from your local IKEA (you'll find it under coffee, their web site sucks so you probably won't find it by searching for "milk frother").
Remove the coiled wire from the end. Thread the shaft into the fan and carefully press it down. Try and get it centered. Turn on and enjoy the cool!
If the fan turns backwards reverse your batteries (it should turn correctly out of the box).

How did you come up with the ingenious connection? What if you didn't have space between the blades for the circle to get through? Could you imagine a push and twist connection?

I found you can search for it by just searching for 'milk'. It's $2.99 in the US.

Search for Produkt. I needed the link for the US version which has a different product number so changing gb/en to us/en didn't work. Sucks you can't order online. Getting to the "local" store sucks.
