I needed a tool that would catch the dust from drilling in concrete and save the time I would have spent laboriously vacuuming the floor, useful when we have many holes to drill. It has four tracking points.

I'm setting up a new nano aquarium, aquascape and cardinia shrimp. My new Aquael Versamax Mini had a water intake to the filter that was too short, so I decided to make a kind of extension and at the same time add a skimmer that floats on the water surface :)
