A positive battery terminal cover for a Dodge Magnum. They no longer make the part.
Supports are needed. A small piece of 1.75mm filament is used as the hinge pin.
Printed at .2mm
Infill was 20%
Was printed in PLA and has held up just fine. But this is in an engine bay so you may want to chose a more heat resistant filament.
