Printed on a Fablicator!

EDIT: The Impeller I believe is backwards. It still works very well, though. I'm going to re-print a mirrored version to see if it makes any difference.
EDIT2: The impeller works about the same despite being right or left handed. go figure.
Instructions
Wear Safety glasses when first turning this on! The impeller tips spin at 200mph and will not hesitate to injure you if the impeller comes apart! Make sure the print is very good quality before spinning it up! Use at your own risk!
Print all 3 pieces.
Screw the neck onto the Dremel until snug.
Thread the Impeller onto the Dremel shaft. It might be a little tight, but will go on with a little effort. It must be threaded on completely, so there is ~1/16" clearance between the bottom of the impeller and the neck. Be careful not to break the blades, though!
Attach the shroud. The alignment pins should all line up and snap together with the alignment holes. Screw the neck and shroud together with (6) 4-40 X .25" screws.
Congratulations, your Dremel is now even more multi-purpose!

This looks awesome. I wonder if a tesla turbine style impeller would blow as well with more durability. I'll have to make this and try it with my rotozip.
I would like to print a smaller version, but scaling the impeller would lead to too thin fins (say it quickly!).
I
had a look at the Solidworks file, but it seems that you use an
external tool to generate the part. Do you have the source of source?
I printed the impeller and then wiped it down with acetone to strengthen it. It spins very fast on my dremel. I'm kind of wondering if it wouldn't be a good idea to lessen the amount of fins and make the rest of them a little thicker?
Awesome little thing... printed one in PLA then investment cast it in zinc for fun. Way cool.
Does it blow good enough to replace those $5-10 compressed air spray cans for cleaning dust off the computers?
it moves a lot of air if the dremel is on high speed... a lot of air
For cleaning general dust out of a case, absolutely. You might still need a dust can/compressor for crevices, though.
I'm going to guess 60mph exit speed. Maybe a little higher with a reducer.
I guess this was the last piece for anyone who would like to build a 'Free as in speech'-robotic vacuum cleaner! NICE! Thanks!
I was Just wondering if anyone had made a nice turbo impeller - yup. This is just awesome

Nice! But was tricky to print for me, the horizontal tube it only attached to the bed with one line. It comes of really easily.
