55 Gallon Drum Funnel
Description
I made this 55 gallon drum fluted funnel for our waste coolant for my auto repair shop. The flutes help with channeling the fluid down into the barrel. The funnel is threaded for a 2"-11.5 NPT thread. The print is already reduced for thermal expansion of the filament. So you should be able to print this and thread it directly onto your barrel. The print in this photo was slightly on the smaller side and threaded in really easy. You may want to test just the thread part and make sure it threads ok on your barrel. If it's too small, just increase the X & Y by 0.5%. Same with the locking ring. Screen had nubs on the sides that mesh into the flutes. If you're using chemicals, like oil, brake cleaner or gasoline, you're going to want to print this with a filament that is chemical resistant such as polycarbonate or PETG. Print this upside down with the large opening on the build plate. ***NOTE*** If you are in the southern hemisphere (south of the equator on this planet), you need to use the funnel and screen files labeled 'southern' at the end, so the flutes go in the correct direction.
