3D mini Pinball: Additional parts

I added some supports on the Base to make it possible to print it standing upwards with minimal support to print it on smaller build plates. The supports also are good for the table, specially if you have to split it to fit on you build plate. As I do not have steel balls yet, I used 3D printed balls. But they were always shoot away with the shooter. So I designed a Top cover for the table. Beside that, I do not recommend to use 3D printed balls because they are too light to turn the spins.
