Connect 4 Discs

Summary Continued: 

If so, these tiles are exactly what you need!

Short Summary and Process:

A teacher had a large Connect 4 board that she let students use. It was roughly the same as this example:

I believe this is the link for it: https://www.campingworld.com/camper%27s-choice-giant-glow-in-the-dark-four-in-a-row-game-761104.html 

I was tasked with designing another version of these discs that the students could use to have more than 2 players in one game. Luckily, I got a reference that I could use for measurements.

After calculating a radius, I created a sketch that could be revolved around itself.

I also added a fillet to the top surface of the shape, but kept the bottom flat for printing convenience purposes.

After this printed out with multiple filaments, a circle shaped pattern formed which looked ugly. Fortunately, the teacher was lenient and accepted it the way it was.
