MPCNC Dust Collection (25.4 version)

MPCNC Dust Collection system using the conduit as the pathway for the dust shoe.
As such, removal of shoe is easy without tools, allowing for easy bit changes.

Attached is a nut wrench with indicator lines for depth to hold nuts as the MPCNC nut retention design needs to be removed to allow for proper air flow.

Bottom simply "snaps" around conduit and pushed up inside.
Top slides easily into upper conduit location.

I used bristles with a top thickness of 6mm. It slides easily in channel on bottom of shoe and is held firmly with hot glue.

This design should be universal to all spindles, but I have only tested with the Dewalt 660
