Optic fiber picatinny iron sights

Hello, I made this optic fiber iron sights for fast aiming during my airsoft games, it uses a 20mm picatinny rail so it's basically universal for all replicas. 

I used three pieces of 2mm optic fiber that i bought on ali for cheap, but they are not mandatory, you can even cut pieces of your filaments and glue them in so you can use whatever color is better for you :)

Pla is great, but petg or other filaments are stronger, your choice.
