Bean animal overflow help

[SnakeBlitz33]

Ok guys and gals,

I'm adding a bean animal overflow to my tank and I need to know some comfortable to work with glass dimensions for 1" bulkheads. I would also like some input on glass thickness as well. Oh, and I would like some ideas on how to paint it black or conceal it somehow.

Black krylon fusion spray paint worked great for me.
