Fiber Optic "Red Dot Sight"

Description:
A fiber optic sight for nerf/airsoft that has a similar profile to a red dot. Two heights are included. Heights measured from the top of the picatinny rail to the base of the lens.

1. Short: 21mm
2. Tall: 25.5mm

Materials:
1.5mm Fiber optic rods in your choice of color
1-2 M3x30 screws
1-2 M3 nuts

Printing Instructions:
No supports necessary. I recommend PETG with 4 walls and 20% gyroid infill, but PLA should be fine.

Installation Instructions:
1. Insert the fiber optic rod through the aligned sight posts. I like to make it just a bit short so that I can make it more flush in step 3.
2. Use flush cutters to snip the excess of the rod.
3. Push any remaining into the post.
4. Install on a picatinny rail.
5. Secure in the valleys with the two M3 screws.
6. Secure the M3 screws with the two M3 nuts.
