Sorry about late responses to earlier questions,

the prop and adapter came from hobby-town. just make sure prop. adapter fits a 5 mm. shaft and has a nose-cone for a nut.

prop. : approx $3.00

prop adapter : approx $8.00

the fan guard is from the ends used to ship rolls of laminates.

I can get those all day long. anyone wanna tackle a cool project like this and need the fan guard, let me know.
