Just a simple turn table which uses a std 608 ball bearing. I suggest you print out the parts surrounding the ball bearing first to make sure you get a snug fit. (on my printer attached models fits perfect at 100% scale)

I have attached two sizes, one with outer diameter of 260mm and one with 200mm.
