Sweat gutter head band

When sweat gets into my eyes while riding, it's bad, if it carries sunscreen into my eyes it's terrible. I tried buying single use sweat gutters and a reusable one, they didn't work for me. So I designed this and printed it from TPU and it's great.

Make sure to place it on your forehead, just above the eyebrows with the smaller area against your skin so that the beveled edge is upward and creates a channel for the sweat to pool into and runoff to the sides.
