This Christmas decoration star is illuminated with an RGB LED strip.
I designed it to have a nice advent decoration with functions also as an ambience light.
Some details about the designing process you can explore in my video. (German language)
The parts are designed to print with a extrusion width of 0.4mm. Why this is important i explain in the video. But for short, it is because of the vertical wall thickness is 0.8mm.
Some slicers like Sli3r need a extrusion width settings of 0.44mm to get perimeters with 0.4mm width.
