175

A mini ball machine that uses 4.5 mm ball bearings. It does work, but because the margins are very small the tolerances on the gears a just a bit too much to make it work fluently (the gaps do not line up perfectly sometimes).

But even if it works reasonably well, it took a few tries to get to just that point. But it still a little fun build.
And when the ball is on top it will run down the back of the mechanism and end up at the beginning.
