This is a dust extractor for a mini mitre/circular saw that I use to cut archery arrows to length (the saw is currently available under various brands on Amazon, eBay, etc.).

My mini saw had an unused 4mm screw hole on the right hand side and I thought I could add a dust extractor in there.

The extractor is made of three parts that must be glued together after printing, and then the whole thing is fixed with a 4mm bolt. The end adapter needs to be printed with supports. It fits a standard 35mm workshop vacuum hose/tube.

Also included is a round protective cap for the bench clamp.
