Automobile Rusted Panel Cover

I can't think of a better name for this. If you come across it and can think of something better send me a message. So this is a 3D Printed "patch" of sorts for the Gas Cap on my Ford Ranger. My Ranger had a spot of rust on a corner of the metal gas door/flap. It had pretty much eaten through the bottom left hand corner.
I cut off the rusted corner of my Gas Cap door/flap and created this as a creative aesthetically pleasing patch that i've printed several times with a variety of material
