Drill Dust Collector Vacuum Attachment

I designed this quite a while ago and never got around to uploading it. The drilling contest encouraged me to finally upload. I designed this in FreeCAD early in my drafting education, so I may not have used the best drafting practices. It is parametric, so you should be able to adjust the port size for your vacuum cleaner hose fitting. Adjust the “Socket-FunnelInteface” sketch OD to slightly larger than your vacuum cleaner hose, and the “SocketEnd” sketch OD to slightly smaller to get a slight cone shape that should wedge into your vacuum cleaner hose.

Connect your vacuum cleaner to the round nozzle ("socket" in the named features in the FreeCAD file) and turn on the vacuum. Hold the “sharp” edge of the collector flush with the wall below your intended hole location. Line the top edge with the horizontal centerline of the hole (to center the chuck relief with your drill). Drill away, and the circular relief should provide clearance for the chuck on your drill. (It does on my DeWalt.) Watch the dust get sucked down the hole and not scatter on the floor.

I suppose you could attach a bag instead of the vacuum cleaner and just let gravity pull the dust down. I'm not sure if it would be more effective than the suction of a vacuum cleaner. But it would certainly be less awkward than fighting the vacuum hose while trying to drill high on a wall.

I printed mine in ColorFabb PLA/PHA Signal Yellow only because I've found that color is a close color match to DeWalt Yellow. If you print it in the design orientation you'll need supports. But if you print with the vaccum cleaner socket down as in my pictures no supports are needed (but you will want a decent brim as in my pictures).
