Bath Drain Strainer Plug

We didn't like the large silicon hair strainer for our bath, so we decided to design one that would fit in the drain for a more integrated look. It still strains hair without being in the way as we use the shower. I figured I'd put it here in case anyone is looking for something similar. The strainer is 11 mm tall, 22 mm in diameter at the top, tapering to 20 mm at the base, and it sits in the cross braces within the drain itself.
