About this 3D model

This thing was made with Tinkercad. Edit it online https://www.tinkercad.com/things/1V06wyHlaqE See the full story on my YouTube Channel:https://youtu.be/clrfA94Bxco The segments fit snuggly into the slots to form the numbers. They can easily be removed and flipped over to disappear or appear depending on what color is showing. I printed this with Red and White, just pausing and swapping filament at the proper time. You could also just paint the lettering and one side of the segments.
