Anti dazzle Cap - Brompton stock front light

My stock Brompton front light - made by cateye - is a powerful light for everyday commuting. 
I can see in the dark, but sometimes, I think I may dazzle pedestrians, or even car drivers ! 

It's not possible to tilt down the light a little bit, so I designed this cap.

I didn't lost my powerful front light beam, I hope it helps reducing the upward beam.
Access to charging port is preserved, also side lights beams and ON/OFF switch.

Better printed in PETG for outdoor strength.
