Whenever we cut dry walls inside the house, everything is covered with fine dust no matter how much effort we put into covering the furniture.
The attachment shown here is an easy way to solve the mess and avoid the dust. It collects all the dust generated when cutting stone and dry walls. Of course, one can buy such upgrades but I had nowhere to buy it during the weekend so I built my own.
Made from 2 mm sheet metal and mounted to the grinder using modified blade guard.
