Strainer filter / Sink filter / Plumbing drain

Has it ever happened to you that your jewelry or other small items fell into the water drain?Here in Germany, we use a drain in the bathroom sinks that does not have a strainer to catch dirt and objects. In addition, it has a silly, "plus sign" shape. Since I couldn't buy one anywhere, I decided to design and print one myself. It fits beautifully, catches both dirt and fallen objects. It is easy to print, easy to install and just as easy to remove. I recommend it to anyone who has such a drain system in their bathroom sink.Dont let your things flush away. :)Boost MeEvery boost motivates me into further works. Many thanks!
