12V ("cigarette lighter") hook

thingiverse

I was in need of something to attach a trash bag to my truck's interior and I never utilize the 12-volt outlets. This design fits perfectly into one of them.\r\n\r\nThe quality of your filament will greatly impact how well this works out. PLA has some give, so it might be better suited for withstanding pressure against the sides.\r\n\r\nIf you print this model lying down (using the flat backside as a makeshift shim) you may experience more success, as printing vertically can lead to delamination and layer breakage. To achieve this, however, you'll need to print it with supports in place.
