Print the case with PLA and 0.2mm layer height, 2 perimeters and 20% infill and no supports! Ok, we need to paint the case a little bit since white doesn’t look that good. So, we sandpaper it a bit. I first applied a coat of primer. After a few hours I’ve sandpapered the case again and then I’ve used some spray paint and paint it black. If needed we can apply more than one coat of paint. I've also painted the buttons with a gold color.
