The '92 Ford F-series 3D-printed model is a excellent model that requires little work before painting. The area requiring the most pre work is the front hood (it's obvious from the print layers that the model was printed at about a 45-degree angle). Still, the print layers are thin so a little putty and a little sanding takes care of it. If you're adding running boards, the bottom edge of the body sides are slightly wavy but filing is easy.
