Clip for folding workmate sawhorse

This was an impossible-to-find clip that held together a folding plastic saw horse in the collapsed position. 

I made several versions. 

Since the original clips broke I made a few optional ways to use it. A PETG version works but the clips can be brittle during install so I made a version with more of a comb style back end. I tried making this style out of tpu too but it was too flimsy. Then I made a petg insert and a TPU outer and it was just right! I also made a bolt-together version that fits a #8 nut and screw if the plastic has broken to the point where clips won't work anymore.
