Boat Floor Vent

I needed a new floor vent for the ski locker in my boat. The original was flimsy and broke easily when stepped on. Printed in standard PLA with 3 layers top, bottom, and sides. Gyroid infill 25%. The small diameter is 4", and the large diameter is 5.6". The overall thickness is .5".

UPDATE: The above measurements were the published dimensions for my Chaparral ski boat. However, it fit perfectly when printed at 95%.
