6x9 speaker grille. Printed as two piece with some spacers if needed. These were made to fit over 6x9 speakers that are surface mounted on plywood. Speaker sizes vary between brands, so make sure of your dimensions before printing. Best results on the cover were at 40% cubic infill, the ring at 20% standard infill. For both cover and the ring I found that using a brim helped to reduce warping and lifting at the edges.
