Dust Blower accessory for Dremel 4000 CNC mount

The first time I ran the Dremel while mounted to CNC, I noticed that all the air generated by the motor blows out one side of the Dremel. So I designed an attachment which directs the airflow from the Dremel vent to blow dust off the working surface! The amount of airflow is, of course, dependent on the speed the Dremel is running--so higher speed means more blowing power.

This accessory fits directly to the mount I designed: http://www.thingiverse.com/thing:599893
