RailRiser-W-Sightguard.

I used this as base: https://www.thingiverse.com/thing:2794182
I removed the logos because you need to print in very high resolution to be able to print them, otherwise the logos print awful. I also improved the errors in the holes in the original model

There is another from a rail riser in this page: https://www.thingiverse.com/thing:2475236. I added a bit of inclination (0.5deg) to the riser and the lens protector in one piece.
