Industrial bottle lid/lid with funnel

thingiverse

I use these 10L bottles to dispose of old oil/fluids from servicing my cars. The 5L oil bottles sometimes weren't enough, so I got some of these bottles and started using them. Sometimes, putting too much fluid in the funnel caused it to spit fluids back out. So, I printed a lid with a large diameter funnel and vent line. There are several versions: a quick lid, a full lid, a lid with funnel, a lid with funnel and vent. There's also a gasket for the lid and a vent end that faces the vent away from the fluids entering the bottle. This prevents oil from spitting back up the vent line or the funnel. You can't realistically pour fluids in there fast enough to fill the funnel, but it's still a good safeguard. The lid is 2 colors because I ran out of filament and printed a new section. Then, I used my 3D pen to add the rest of the body. The lid was printed in PLA and has held up fine to solvents and fluids so far.
