Kitchen extractor hood clip

This is a clip which I designed as a replacement for a broken clip from a kitchen extractor hood. I'm not sure what make of extractor hood it is, but you should be able to recognize the original clips from the image showing the broken clip. The clips are required to lock the underside of the hood (where the grease filter is located) in place. There are 2 clips, one on each side of the under hood cover. There is a small slot on the underside of the replacement clip to allow the clip to be turned,
