had few of these laying around, have to say that they work really well so I've decided to make a cover case to use them as big blowers, good for diy pèrojects that require much air.
u'll need

3 m4x30mm bolts+nuts

10 m3x30mm bolts+nuts

really simple to assemble as u can see in the photos.
hope u will use them for something strange, mine will go in my co2 laser cutter

SUGGESTION: to use them at 12 volt max power joint gray and red wires
