Vacuum cleaner to G1/4 adapter

Have you ever wondered how much of a vacuum is actually created by your vacuum cleaner if you block the nozzle? Well, I have ;-)

And since I have made it a habit not to give up before I have measured a certain physical parameter that I got interested in, I have purchased a cheap vacuum manometer from Amazon (around 10€) and have designed and printed this thing.

I could not find a way to create the G1/4 thread myself, so I was glad to find the referenced vacuum chamber adapter, which I have re-mixed with my own design of a 1.25 inch vacuum cleaner adapter.

And here is my measurement result: About -5inHg or just below -200hPa.

If you print and test this thing, pleeeeease:

Post a picture make and tell us about your results. The world is still lacking a global vacuum cleaner max-vacuum database.

Be very careful not to overheat your vacuum cleaner, which is using the intake air to cool the motor. I will not be responsible if you ruin your vacuum cleaner.

P.S.: Please don't tell me that this is one of the most senseless things on the internet. I perfectly know that myself and I will not argue about it. I was simply obsessed with figuring this value out and maybe I can help some of you to overcome your own obsession ;-)
