Umpire Indicator for Baseball. 

The indicator is fully working and is designed for printing with two colors. It is possible though to print with one color and just write the text with a permanent marker. 

This design works without gluing. 

Before printing clean the adhesion plate well! Without a good adhesion the writing will look awefull. 

Check the right location of the wheels before complete assembly! 

I'd suggest to break free the cogging mechanism before assembly, but it works after aswell. 

All wheels only rotate clockwise!

If you want one with the strike wheel rotating counterclockwise just write a comment. I could make one easily. (Some commercial manufactures do rotate that way, others dont)
