Vacuum attachment for a DW660 cutter. The vacuum attachment side is for a Fein vacuum hose ( the female part of this printed part is 1.35").
The part is shown here on a modified Shapeoko 1.
I have been using it with EPS foam, which produces very light dust. I have not yet verified its pickup with other materials (most likely will not pick up metal chips).
Print the vacuum duct with support, it takes a bit of effort to clear it out, but I believe it is necessary.
The clip print holds the vacuum duct on, hooking onto the groove that the router foot attachment normally attaches too. Please take notice of the anti rotation stop in the groove, as the clip will not work if it is inline with the stop.
