3D printed threaded collar for a Dremel

(1/3) > >>

A7er:
I thought that my Dremel needed to be mounted in a pillar type drill mount, one of those accessories that take a pistol drill. I measured the thread on the Dremel and drew it up in Designspark then printed out a test piece to see if I had the pitch right before printing the whole thing. It was a bit tight so I altered the design and printed another test piece which fitted perfectly. I then printed a collar that the test piece could be glued into. A simple thing that could possibly be bought, but now I have the sizes in my cad programme I can make other accessories.

As long as you're into printing accessories for your Dremel you might want to think about a fan for blowing dust/swarf away from where the tool is working.  Dremel sells such a device (pictured upper right in the first photo) but it's incorporated into a collet closing nut for the device.  I use an adjustable chuck (pictured) so I hand carved a miniature fan out of plastic (lower right) since I don't have a printer.

It works so well that I keep it on the Milwaukee hand tool all the time now.

A7er:
Thanks Marv, I've not printed a fan before. I'll see if I can make one.
I wonder if it can be made into a dust extractor? Instead of blowing the dust away.

Nifty fan! I do a lot of wood carving with the rotary tools, and to keep the dust under (some) control I built a large box, open towards me, with a grid of surplus computer muffin fans in the back wall. In front of the fans is a standard furnace filter - when I change the filter in the furnace, it goes to this box for more use. The filter needs to be vacuumed out after a carving session. It catches most of the dust, some of the fine stuff still blows around or sneaks past the filter, but it catches a lot. As the dust comes off the tool, you can see it turn in midair and get sucked into the filter (tiny little screams?)

bent:
I don't think my Dremel has a thread like that on it, but that's a cool idea.

I like crueby's dust blower too...though I'm using my 3d printer to make a working dust sucker out of our old, broken Dyson vacuum cleaner.  So far I have it working ok as a cleanup, and have plans to create some clips/mounts to hold a suction tube near the milling face on the mini mill and/or mini lathe.
