Dremel Impeller Blower

USE THIS DESIGN AT YOUR OWN RISK AND KEEP THE WORKING ASSEMBLY AWAY FROM SMALL CHILDREN. IT MIGHT TAKE OFF A CHILD'S FINGER TIP AT HIGHER SPEEDS.

I really liked the concept of Landru's Dremel Turbine. I decided to try to make something smaller that blows a lot of air. I also wanted to be able to mount it and remove it without having to disassemble it.

This one was designed to fit and tested on the battery powered Dremel 8100.

This one uses an impeller design from Grabcad that I modified. I scaled the impeller down to be the same diameter as Landru's. I may make a larger version later, stay tuned.I took out every other blade and reversed the direction of the blade ends where they are throwing the air out of the nozzle. No engineering involved, just thinking about how it would work.

The other change I made is that this one mounts right onto the "Dremel chuck" via a press fit. It is tight enough to stay on without something retaining it.
