I know, I speak for many people when I say the worse thing to be in the air is the dust left behind when sanding sheetrock joints. With this sheetrock sanding vacuum attachment made for the Rainbow E2 Series Vacuum Cleaner, you will be able to reduce at least 95% of the fine dust in the air (the heavy dust goes straight to the floor). I printed and tested my design an it worked like a charm, the fine dust that lingers in the air was gone. The other benefit of this sheetrock sanding cleaning vacuum attachment is that the wife was super happy that she did not have to deal with the fine dust that settles on top of everything after I finished. I printed this on a SeeMeCNC Rostock MAXv3 at school; .20 layer height; 3 walls; bottom thickness .8; Temp 194, initial temp 205; No support.
