Super easy and useful paint mixer. This is sized for the normal 66mm can size. It is slightly oversized to be able to fit all different can designs. Mixing paint has never been easier. This simple tool attaches to any drill. Works with any standard aerosol can, spray cans, spray foam, paint, oils, bedliner, and more. Mixes paint better, faster, and more comfortable. Some of the cans I have tested have a lip that is 68mm in size, these also work. Just slide the can in the sleeve with a paper towel or two wrapped around it (to grip the can). All you need to complete, is a 8mm bolt about 40-50mm length, 2 8mm washers and 1 8mm nut. Once assembled place it into a power drill and your off to the races. The hole is offset by a degree or two, to allow for a slight oscillating movement that utilizes the ball in the can to mix the paint thoroughly. I have upped the infill percent around the hole, so it is stronger where the bolt attaches. I have brought back 2-year-old paint cans with this tool. No more shaking and mixing by hand.
