I've been looking for answers to my question, on if i can use Flex to open this ring, if not, maybe i should model it open with configs any thoughts? I've not had much experience with the flex command. But so far i've not been able to get this to flex open. Any suggestions. I am looking to make this out of nylon, it'll be molded as open, and be a flexible clamp that can close around a foam hose.
