Modified compressor.

You 3D printed something that you are running compressed air through? That's slightly frightening. Hopefully it's over-engineered.

Check out Tom Stanton and his 3D printed compressed air engines.

The walls are reasonably thick.
I was only using it at pressures up to about 1/4 of a bar so no worries. But i tried testing at much higher pressures just in case by blocking the output and letting the compressor have at it with all it can give. At that point the hose started pooping itself off the output from the pressure, so i held the hose down to prevent it from doing that, that made the pressure go even higher but eventually the hose expanded enough to start leaking around connection point. So it most definitely can hold quite a few bars with no issue. And even so my hoses pop off before it gets there as safety.
If you wanted to approach something like 10 bar tho, then yeah you have to be careful, but at a few bar its no biggie.

Ah ok, my air compressor is typically set to around 125 psi, and a refrigeration compressor, if not monitored can produce several hundred PSI in some cases so it's worth being careful. Don't underestimate the amount of carnage you can have with the failure of any sort of pressure vessel. It may not occur to someone that their system is running much higher pressure than yours.
