Summary

Edit: The O-ring one seems to do more harm than good from my experience, but I'm still leaving it in case someone has better luck with it. The air leak isn't all that impactful, but I'm not particularly a fan of it.

Yeah that title's a mouth full, isn't it?

The short of it:
It's an adapter for the GEDSTMDRK portable airbrush compressor to a 1/4" adapter allowing you to use a hose instead of having it attached to your airbrush.

The rant of it:
So once again, facing the consequences of being a cheapskate, I bought the most popular and cheapest airbrush on Amazon to test the waters and see if I enjoyed using them.
(see here if curious, but avoid purchasing: https://www.amazon.com/Airbrush-Kit-Compressor-Rechargeable-High-Pressure/dp/B0C9TL5YCS/)
This turned into a disaster because the battery in the compressor lasted only around 40 minutes on the lowest PSI, so I'd spend more time cleaning the airbrush then actually using it.
My first two considerations were to either buy a long USB cable to charge it while I used it, or a proper airbrush hose and just make my own parts to adapt it for the airbrush and compressor. For the sake of comfort, I went with the latter.
I'll skip whining about the hours of trial and error in attempting to design my own adapters with very limited CAD experience (in my defense, you have to get the measurements PERFECT for the hose to work without leaking) and say I decided to just remix this part for the sake of tried and tested measurements and ease of printing.

Now I don't know if all of these cheap portable air compressors are made with similar measurements, but I figured I'd put this out there for the 1 other person on Earth who might have the same need as I had.

Just some friendly tips:

-It may seem very straight forward putting this on, but if it's too tight around the inner nozzle inside the compressor, it can very easily knock the button out of place and getting that back into place is a huge pain, so try and find a happy medium where there's a small gap around it to prevent that.

-The airbrush-side hose adapter isn't perfect, so if it doesn't work I may advise just attempting to remake it yourself. In my case, I just super glued it on to the hose to seal it up. Using O-rings is advisable here.

-If you're using this for a similar reason, I'll be up front and tell you that charging the compressor during use really doesn't extend usage by that much.
What I can tell you is that if you remove the battery, strip an old usb and give it a 2 pin JST-PH male connector, you can run the thing for as long as you need. Even with an old power bank, I never got it to run out of power after a couple days of use.

(This is a warning from my own stupidity if you decide to use the connector from the old battery:
One, I don't advise doing this and liability is on you yaddayadda.
Two, If you do this, be sure to snip the positive and negative wire individually. A "momentary" lapse in reasoning gave me a little light show which could've potentially been much worse)
You won't be able to screw the back end back into place, but I may be making something for this that I can share later on.
