Impala 1960 coupe scale 1-12

This is .3mf project with lots of floating parts, and negative parts made with Bambu studio, and printed on P1S .

The tail lights are not 3d printed, they are actually cut from pens.

The shine on the assembled model is because I sprayed it with a clear gloss coat, it also made the color darker. the unassembled model is less shiny, and lighter.

In one of the photos of the 3d printed model, you will notice this annoying banding or pattern on the hood, and until some expert decides to print this project, and tell us how he managed to get a smoother surface, here is what I think based on tests, comparison, reading, and of course advice from the community.

Perhaps the original model when it was first exported it wasn't exported at a fine resolution. Why am I saying this ... because I've printed this 20 hours project 3 times, and made several tests on samples at slower speeds of the outer walls, and higher temperatures at different flow rates( 0.93-1.03), and readjusted XY, and Z belts, and I only get this same exact pattern on the outer side of the shell, while the inside is very clean, and smooth, Maybe because the inside was cut clean by negative parts in the slicer, while the outside surface was original, but as I said the roof, trunk, and hood were remodeled almost entirely.. but they still get this same exact pattern only on the outside... the inside is clean and smooth... and two models are printed at 100 mm/s outer wall speed, and they look exactly the same as the 1st one which had the outer walls printed at original speed 200 mm/s
