drain tee

While learning to model, I found that the drain pipes for the washing machine and sink in my apartment were squeezed in, and the hoses were deformed This caused the sink to drain very slowly The basin would fill up quickly with the water running, so I thought about making a drain tee to practice with My water pipe is 32mm, so I designed it based on that The main drain pipe should be 40mm, so I set the outer diameter of the outlet pipe to 37mm and the two inlet ends to 33mm If there's a slight difference in the pipe size, you can axially trim the hose during installation, and it will fit easily
