Watertight floor drain 水封快接地漏

I am terrible at English. This is a Floor drain for CORONAVIRUS !! Recently, there have been cases of people getting infected with the coronavirus through sewage in Hong Kong. To prevent this from happening, I designed a floor drain that can be easily installed in your home. Here's how it works: if you have a direct pipe connected to the sewer system in your home, print out this design and connect two pipes to it. The water will collect in the middle of the drain, preventing any contaminated air from entering your home. This is version one, so bear with me while I make some changes later on. ### Version 2 I've added more space at the bottom of the design, making it easier to remove the supports. ### Version 3 I've thickened the walls to 5mm and optimized the structure, allowing you to print without any supports. ### Version 4 I've increased the size of the drainage hole and rounded off some corners, which should make printing without supports even easier. The model is quite small, so you can scale it down to fit your needs. Just printed this out and it works beautifully! If you have a washing machine drain that's connected to the sewer system, just shrink the model down to 50mm and you're good to go. ### Version 5 I've added more space at the bottom for drainage and increased the size of the drainage hole. I've also included two separate STL files: one for the outer shell and one for the inner core. Don't print these files separately, though! ### Instructions The inlet on top has a diameter of 5cm, while the outlet on the bottom has an external diameter of 5cm. You can scale this design to fit your needs. When installing, remember to seal both ends with waterproof tape and connect them securely to the pipes. For maximum safety, consider sealing the entire exterior with tape or plastic wrap. I've uploaded the F3D file for you to download. ## Go, world! Go, China! Go, Wuhan!
