High Powered Straw Suction Unit?

[rg12]

Sometimes I need to vacuum a really narrow area (2mm and less) with quite some power.
Is there a machine that can do that?
Thought of dental suction but that's way too weak for my need.
Any ideas?

Maybe get a reducer for your normal vacuum 3d printed?

Maybe find a pvc end cap that goes over the end of your vacuum, drill a small hole, and insert a straw?

Power?
You won't get much airflow through a straw.
Perhaps: Use your compressor and a Venturi with a port located in the low pressure area

Thats the best idea.

power wont get you anywhere, you could be Superman sucking on it and it wouldnt matter.

.....the maximum theoretical vacuum at sea level is 29.92 in. -Hg, so you must rely on flow ( rate) to create a speed ( increase) that will bring the venturi action into play, and pick up the (litter).

I feel kinda dumb not understanding that...
Why will big power (regular vaccum cleaner for instance) with a super small hole work?
The only thing I can think of is that it will choke the motor from not being able to move at the speed it "wants" to while still drawing current and heating up.

Assume you are trying to suck up dirt from a small place. Try a normal shop vac. Vacuum the narrow area and everything all around it. Sometimes I hold my hand on the vacuum nozzle to get in small places.

-Or-

Air compressor with blow gun. Blow dirt all over the neighborhood.

Remember in shop class when the teacher told us about blowing air at people as a joke.

•Compressed air accidentally blown into the mouth can rupture the lungs, stomach or intestines
•Compressed air can enter the navel, even through a layer of clothing, and inflate and rupture the intestines
•Compressed air can enter the bloodstream, and death is possible if it makes its way to blood vessels in the brain
•Direct contact with compressed air can lead to serious medical conditions and even death
•Even safety nozzles which regulate compressed air pressure below 30 psi should not be used to clean the human body
•As little as 12 pounds of compressed air pressure can blow an eye out of its socket. If an air pocket reaches the heart, it causes symptoms similar to a heart attack. Upon reaching the brain, pockets of air may lead to a stroke.

Tickle the small area with a tooth pick or whatever ya got. Hold tooth pick with one hand. Hold shop vac vacuum nozzle with your other hand. This is why we have two hands.
