Not for my LJ, yet... but I printed a few things for my F150 before I lost use of my 3D printer, most notably: a custom mount for my winch control box that mounts underhood, to the side of the battery box bumper fillers to cover the access holes for the in-bumper winch (the one one the right has been cracked for 3+ years but stays in) hubcaps & fillers for my winter steelies... with Plasti-dip and a little plastic, they almost look custom. But more importantly, they keep the salt out of the wheels. All this stuff is PETG and has been used on my truck for more than 5 years (alright... the wheels, only Dec - Apr). I really need to get another printer. I have all sorts of ideas for the LJ.
