Venturi for toy leaf blower

thingiverse

Bought a toy leaf blower ($10) at Cracker Barrel to use on keyboards and other electronics. Felt a quite of bit of air reversed out of the intake from the turbine blade. I work on motorcycles and searched for a carb venturi but none were exactly right when minimized to the size. Using TinkerCad I created my own. After epoxying it on to the intake there was no air escaping and a slight increase out the nozzle. Raining here today so this was a cool project to create.
