Fun-made clock dial

As I get familiar with 3D Printing, I started to track the evolution of desktop monochrome 3D printers’ capability. Once I heard that changing the filament during the printing process can produce a colorized object layer by layer. I always wanted to try it out, but I had no idea what kind of object can demonstrate this “hack” tastefully. Then my clock went wrong and I was wondering, where I can buy a more relaxing and “warmer” one than the previous was. It was ridiculously obvious: I can make it on my own, and the clock dial is a perfect way to try out mentioned “hack” and get my first duochrome stuff printed with two kind of PLA filament.
