Kitchen and Shower drain strainer

The kitchen and shower sink drain holes were too big, so I had to design something that would fit for my kitchen and shower. It has very tiny holes, so it stops almost all particles from entering the drain, but the water can flow easily and clearly. Also has a handle for easy removal.The kitchen sink drain was slightly concaved, so the upper circle radius is larger.For the kitchen sink strainer:Total depth: 9.5mmUpper diameter: 45mmLower diameter: 41.5mm For the shower sink stainer:Total depth: 8mmUpper diameter == Lower diameter = 42mm (the shower stainer is not concave)You can scale down or up, based on the measurements provided, and your own drain's measurement.
