To decorate my JJRC 1:18 jeep wrangler rc car, I search all over the 3d model websites, finally I found this the closet to what I desire, so I downloaded the original stl file from printables.com, resized it to 1:18 scale, make it looks like an expedition case usually found on those offroad cars which travles through no-man lands. Printed on my A1 mini, with 5% infill(otherwise the model will shrink too much to print successfully), using tinmory petg fillament.
