marble maze

this maze is made for marbles with 15 mm diameter or smaller. I have a premade maze and a blank maze top that you can download and make your own maze in tinkercad. https://www.tinkercad.com/dashboard
If you want to use a bigger marble you will need to scale it to the size of the marble, and a bigger printer or make it in sections and assemble it later. the maze is set for a printer with a 220mm X 220mm base. you will need to print each section separately. it is built to come apart.
Update 1/30/20: I was looking at the maze top in thing view, and realized that you might need to draw the start and finish on it
