Clip for small pet cage

This is a replacement for the clips used to hold small pet cages together (shown here with our one-eyed rabbit). Our rabbit cage clips keep breaking, but these seem to hold up well. This size clip works on both of our cages, which are of two different sizes, so I'm guessing they'll work on other sizes too. These were printed on a Replicator 2 with medium resolution and 60% fill.
