This is a remix of a remix of one of my earlier designs. Printed one out of PETG and I'd say it's a QUALIFIED success. If you bend the gate ALL THE WAY back you can damage it (see photo), but if you're not actively trying to bend it to the failure point and just clipping it on something it'll be fine. I DO NOT recommend printing this model out PLA or ABS. It was designed with the flexibility and toughness of PETG in mind.
