Skateboard hole drilling jig or 80/20 aluminum bracket

This can be used to recreate the skateboard hole jig as described or you can use it for any other kind of hole jig that uses 80/20 style t-slot aluminum. We wanted the holes to stay perfectly parallel, but we wanted to be able to spread the holes pattern apart for different sized skate boards. I will add another picture once they all print and are being used on our longboards.
