Audi A2 speaker adaptor / speaker ring

Speaker adapter for Audi a2. Should fit speakers that are 50mm tall and 160mm diameter. Modified the rear for better sound dissipation to the door and added condensation drain.I tried to make the hexagons in the same area where the OEM version has holes.The original would not fit jbl stage3 607CF I wanted to install. Modified with Tinkercad. Sorry if it is not perfect.
