Still messing up a little with the Toroidal propeller I designed for my Kids flying propeller :)
Here is a version to mount on your drill.
I see the following areas of application
cleaning the workplace (if no compressed air is available)
starting a fire/ charocal grill
cleaning the floor :D
Cooling down yourself/ friends during a hot day
To use the device you need a 1/4" adapter and a drill with roundabout 4000 rpm for a nice little pocket storm xD
Also I uploaded the flying propeller to have a little fun. To make it fly you have to rapidly lower the rpm of your drill and the propeller will fly away :)
Have fun and keep printin!
I printed my props with PA6CF and GITD-PETG and a 0,6 Nozzle
I like to locate the inner seams at the core part.
