I didn't like drilling plastic (and not doing it well) so I decided to put my 3d printer to use and printed this because I didn't like drilling plastic (and not doing it well). So I decided to put my 3d printer to use and printed this speaker grill in a flower design. A Fusion 360 file is attached for customization :-)

Got the transparent one printed at JLC3DP in a translucent plastic. (They didn't like the thin walls, but I accepted the risk)
