Vacuum cleaner to G1/4 adapter

thingiverse

Have you ever wondered how much vacuum a vacuum cleaner actually creates if you block its nozzle? I have, and since I don't give up until I've measured the physical parameters that interest me, I bought a cheap vacuum manometer from Amazon for around 10 euros. This little gadget led me to design and print this thing. I couldn't find a way to create the G1/4 thread myself, so I was happy to discover the referenced vacuum chamber adapter, which I combined with my own design of a 1.25 inch vacuum cleaner adapter. My result is about -5inHg or just below -200hPa. If you print and test this thing, please: Post a make and tell us about your results. The world still lacks a global vacuum cleaner max-vacuum database. Be extremely careful not to overheat your vacuum cleaner, which uses intake air to cool its motor. I won't 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 Thingiverse. I'm fully aware of it myself and won't argue about it. I was simply obsessed with figuring out this value, and maybe I can help some of you overcome your own obsessions.
