For once I wanted to use the multicolor feature in a practical way and designed this Lipo Case for micro quadcopter batteries. The bottom inside is printed green and red, when the powerchord is on the green side the battery is full and on the red side it's empty. This way I won't lose track anymore which batteries I've already used.
The box consists of 5 parts which can be indivudally colored, the cover has 6 parts. If anyone want's to give each spacer a different color I can upload that model too
