Unlike the original, this one prints the ball along with the Maze Coaster. 

there is also a version with a roof, that you can use if you have transparent filament so you never lose the ball.

-Don't forget to add colour changes!

-If you're printing with the roof, remember to put in the ball before it prints on! (definetley didnt forget once)

-If you're printing the ball, use supports, but only draw them on the ball, because no other are needed. Especially not inside the maze when printing the roof.
