Lowrider 3 CNC extended + tightened lower vacuum dust shoe

Hey, thanks for the this. I'm working on a new approach for a "floating z" type dust shoe. I'd like to also do a tighter fit for the new shoe. How much (in mm) did you need to close the gap to adjust and get the tighter fit? (edited)

This fits so much more snugly than the original I'm amazed that he left it so loose with the original. Thanks for making this, it saved me the time of doing it myself.

Awesome ! Thanks for the design, I wanted precisely something like that; should work perfectly !
