LEGO Othello board

I have a weird bucket list. One remaining item was to create a full-size, playable Othello board, with ridges to avoid discs from moving around. I finally decided to try and mimic an existing board. The result looks pretty close to the original:

Unfortunately I was unable to figure out how to create smooth (and yet flat) discs, but they are at least quite playable. Suggestions for improvements are welcome. I'd also be happy to share more information or even a parts list anyone would like to recreate it.
