In New Zealand we have a brand of handy kitchen container called ClickClack. Very useful until the clips break. Frustrated at having a bunch of containers that had flappy lids I modelled a serviceable replacement clip. I modelled these parts on Vectorworks 2015. There are 3 sizes. They all seem to work pretty well. Not sure if anyone else has this brand or this problem but if you do, here is a cheap, non-wasteful solution. Enjoy.You can print these without supports.
