Many people like colors, so when creating a given work, you should not strive only for the shape and form, but also for the widest possible variety of colors. A raw material called rainbow (filament) is a great help in this. It is characterized by the fact that it does not consist of one color, but contains all the colors of the rainbow, and these colors alternate one after the other. It is not possible to know the color of an object before it is printed. This will only come as a surprise at the end of a successful print. This will make each product creative and unique!
