How to catch debris from a hole saw

How to catch debris from a hole saw. I am installing some 6" wafer lights in my kitchen. I have installed some before so I know how much of a mess this can make and didn't want to have the dust go flying all over my kitchen for me to clean up later. I have seen some people use this contraption before and I know there are products you can buy that do the same think. I decided to make my own. It was an old microwave cover that needed to be replaced anyway. So why not use it for my project. I first drilled small hole in the middle and then made it bigger to fit the hole saw. I taped up all the vent holes in the microwave cover and was ready to go. It defiantly saved time cleaning up afterwards. now you know how to catch dust from a hole saw.

Leave your questions in the comments and I will answer them as soon as I can.
