I've seen threads like these so many times. Using solvents in this way at home is just a bad idea. True, acetone is not as dangerous as some. However, IMHO, it is the gateway drug, so to speak. If this thread keeps going, it is only a matter of time before someone posts the link to the carburetor cleaner video where the guy is using beakers full of carb cleaner at home, on his desk, in his office, a closed window in the background, to soften his prints. Then we'll get the insanity of the solvents people are trying out to smooth PLA prints.

Just stop it already! Eventually, someone WILL get hurt.
