My Pool Cue rack has these clips and they were breaking. I tried a couple of the ones on here but they weren't what I was looking for. This one does work in PLA, it prints flat on its back to ensure that the lines aren't going in the direction of the clip to prevent it from breaking. It also has 2 holes at the base so that it doesn't turn when installed like its one screw counterparts. Haven't tried printing it in TPU but it may work even better than PLA for this purpose.
