I was given a subwoofer (score) but 3 of the clips that attach the dust screen/face thing were broken off. This was designed in blender based on measurements from the 1 remaining clip. My design skills aren't great so the mesh is kind of a mess, but at this scale it doesn't matter that much and prints great. I'll attach some more pictures once I get the clips attached. I'll also tag the subwoofer model to give a better idea of what these fit in, but I've seen similar clips in all kinds of speakers and subwoofers. I've included the blender file if you'd like to make some modifications (or feel like fixing my terrible mesh :D).

The first picture is my final print in the nylon 910, and the second picture are my test pieces while I was tweaking the size and shape of the model (numbered in the order they were printed). Clips 1, 2, and 3 in the second picture were printed in PLA for testing, and the 4th is the final model printed in nylon.
