Hobby Holder 50mm platform

The Hobby Holder painting handle/grip from Game Envy is fantastic, designed to use with caps from standard 20 oz. bottles, making it easy to switch out miniatures as needed without having to purchase additional pieces. I found there were times when I needed a larger platform, though, so I threw this together in Fusion.  It's a 50mm platform that screws onto the threads of a soda bottle (or a Hobby Holder).  Easy-peasy.
