Tank treads needed

I need to know where to find/buy custom tank treads for a project I am doing for a class. The size needs to be roughly 9inches long, 1 inch thick, with the spokes to be roughly 0.625 inches long roughly 0.2 inches wide and 0.1 inches deep

Hi,

That’s a good question.
Please see if any of these ideas help:

Kind regards,
Francisco
