Remix of Peterthinks weight adapter to instead fit a dumbbell instead of a weight bar. Worked great for my CAP Olympic 2-Inch Weight plate. As he said, don't stand the bar on end with weights on it. If the weights shear off the round outer part they will slide down and hit the other weights probably knocking a hole in your floor. Put a small one inch weight on the inside if you like standing your bar up to store it. Print two, they are the same.
