I was sick of my funnel always being dirty when adding additive to my RAM pickup, so I designed and printed this one out of PETG. Sure, I could have bought one for a few bucks, but what is the fun in that. It works well with my truck, is long enough and the correct size to open both filler neck doors and allow the additive to go into the tank. Time will tell if the PETG will hold up, I think it will, but I was sure PLA would not. It should work for other pickups as well with the large tank filler opening.
