Work bench Vacuum cleaner solution

I want to have quick access to the vacuum cleaner in my workbench and avoid taking up the vacuum cleaner all the time. This is my solution to the problem.
I've used 50 mm drain pipe with accessories. Mounted under the bench and only hole drilled in the bench in three places in order to connect the hose at several places.
The connection holes that are not used I put a plug in for maximum suction at the point where the hose is connected.

All parts are designed without regard to the swelling /
