B&W 604 S3 Speaker Grill Grommet Holder

My 20+ year old speaker grills started to fall off. Got tired of my 6, 4, and 2 year old kids destroying the B&W 604 speakers...so, I printed new grommet grill holders, and to my shock, worked, without over engineering them. I truly thought I was going to have to use flex, or model with ribs, etc. Plain cylinders did the trick. Printed in PLA. Grills are on there tighter then when new. Used Fusion 360 to model them.
