Drill dust extractor

This is an attachment for vacuum cleaners. Just put it on the tube of your vaccum cleaner, turn it on and place it on the wall under the place where you want to drill a hole ( as close as possible ).
The extractor will stick to the wall and suck in the dust.

I printed other similar designs, but they caused the dust to swirl around inside and leave dust circles on the wall. I designed this one to keep the dust away from the wall.

Print instructions

You do not need supports if printed upright.

Depending on your nozzle size, use enough perimeters to have solid outer walls. For the thicker parts 20% infill are enough. You could probably even print this with 0% infill.
