Dremel Devil

3D model description

The Dremel Devil is a 3D-printed fan that you launch from your high-speed rotary tool to soar up to 200 feet.

This surprising device, like a number of my projects, started out with me working in the lab alone late at night and goofing off with slightly dangerous tools! Read the full story at

3D printing settings


-The Dremel Devil was modeled in inches, so if your slicer program defaults to millimeters, you’ll need to scale up the part.

The Flying Fan Dremel Adapter needs to be super glued or epoxied to a 1" length of 1/8" metal rod. The rod is then inserted into the Dremel tool's chuck or collet.

-If you push the Dremel Devil too hard onto the adapter, it won’t release. It takes a bit of trial and error to figure out the right amount of pressure for reliable release.

-If your Dremel tool has a brake function when you switch it off, I've found that you can use the sudden deceleration to help the Dremel Devil release and fly farther.

-The Dremel Devils I printed out weighed an averaged 20g, we found that heavier ones did not fly as far.
