Sawdust, pointed away from you

The Milwaukee M18 FUEL rear-handle circular saw throws its sawdust straight off the port. I designed a printed extension that turns it away from you, and it now sells on Amazon.

01Problem

The saw blew dust back at me

The 2930-20 is a rear-handle circular saw, and its dust port points sawdust where you stand. Cutting on site, that meant dust on me and over the line I was cutting to.

02Design

A curve that fits the port

I designed a curved extension that fits over the existing dust port and turns the stream away from you. It attaches without tools. The fit came from printing, trying it on the saw and adjusting.

03Selling it

From one saw to Amazon

What started as a part for my own saw is now listed on Amazon, sold by my studio, for anyone with the same saw.
