The ear is divided in 3 pieces with inner frames to easily fit the led shields (cut the connecting plastic before assemble).

I recommend 5mm thick acrylic.
May require finishing with filler primer or wood filler and wet sanding. I advise printing in White Strong & Flexible Polished as other material will be harder to sand.
Maybe you should mark the option "print it anyway" as the thin sprues/connectors may break during the cleaning process. They are meant to break and only serve to keep the pieces together for shipping and handling, so don't worry.
