Redirects the air flow of the router to avoid blowing directly on the work piece and also extends the lock button for an easy tool change.

The original diffuser was nice but I added some improvements:
-The base is 2 mm instead of 4 mm. More space for the wrench
-Streamlined air channels
-Assembly and button attachment to extend the lock button release
