True story: I have a moisture issue in my furnace, such that it needs vacuuming out. This involved detaching a length of tubing, but that puts stress on said tubing, sometimes knocks other things out of alignment, and involves completing the seal between the wetvac and the tubing with my hand.

I also have a 3D printer. I also have a ChatGPT subscription, and some OpenSCAD chops. I came up with a part which would go into the top of the down tube to the drainage pump, and mostly-seal the down tube itself, with an opening on the side to vacuum out the moisture. This was purely prooompted, I took some measurements, printed bits of the part, refined the shape, and you know what?

It works! I can stick it down there, turn on the (very loud) wet vac, and go upstairs. On a 1.5Ah battery it sucks for a bit less than ten minutes, which turns out to be plenty of time.

So: who made that?

Don't care. I'm waking up warm at night.

Also: me, obviously. ChatGPT doesn't have a fucking furnace.
