Here's a toy miata model I've made as a gift
I've used nail polish as paint, it's my first experience painting 3d prints tbh.
I think more coats would hide layer lines, but this was more of an experiment. It actually took me 2 days to paint it, even with small amount of coats
It's also the first time I've engraved anything with my CNC machine.
It was simple, though I've messed up once and set movement speed to twice as much as it was in my tests. I had to sand down the previous attempt and redo it. But it turned out nicely
