Never up never in tool

This is a Golf product which is used on the green to help golfers become more confident in their putting. The old adage never up never in applies to the product name. I am looking for a smoother design than the PVC pipe that I have been using. I would like it to look similar to a molded plastic cup designed that SKLZ Golf makes but with the arms that extend out 45° each way to provide a 13 1/2 inch opening so golf balls will go in the hole as long as they are hit hard enough even if they were just a little off the cup.
