Custom Coaxial Dust Collector Makes CNC Router a Clean Machine

Everyone loves firing up that CNC router for the first time. But if the first thing you cut is wood, chances are good that the second thing you cut will be parts for some kind of dust shroud. Babysitting the machine and chasing the spindle around with a shop vac hose probably isn’t why you got it in the first place, right?

Trouble is, most dust-management designs just don’t get the job done, or if they do, they obstruct your view of the tool with a brush or other flexible shroud. [Jeremy Cook] figured he could do better with this coaxial dust collector, and from the practically dust-free cuts at the end of the video below, we think he’s right. The design is a two-piece, 3D-printed affair, with a collar that attaches to the spindle and a separate piece containing the duct. The two pieces stick together with magnets, which also lets the shroud swivel around for optimal placement. The duct surrounds the collet and tool and has a shop vac hose connection. In use, the vacuum pulls a ton of air through small opening, resulting in zero dust. It also results in the occasional part sucked up from the bed, so watch out for that. [Jeremy] has published the STL files if you want to make your own.

We’re pretty impressed, but if you still feel the need for a physical shroud, check out this shaggy-dog design that seems to work well too. Or you could just throw the whole thing in an enclosure.

Print your own header shrouds

Don’t get us wrong, printable whistles are cool and all, but these printable header shrouds make us think that filament printers like the Makerbot and RepRap might just be worth their salt. This utilitarian purpose is a departure from the souvenirs, toys, and art that we’re used to seeing from the expensive development toys tools.

The six and ten pin header shrouds are designed for a snug fit that makes it easy to glue them onto the plastic spacers of male pin headers. We use IDC plugs and ribbon cable all the time in our projects, but never seem to order shrouded connectors; this is perfect for us. It makes us wonder what other PCB-friendly printable designs we’ve been missing out on? Surely someone’s been printing stand-offs with threaded inserts, right? If you know of something useful that we can share with the rest of the readers, don’t hesitate to send in a tip.
