Three Dot Nerf Sights

thingiverse

These are a set of front and rear sights that will securely attach to the standard Nerf accessory rail. A great original design by RayvenLover was modified to make the front sight longer, enhance it for printing dots in different colors, and add a friction nib to prevent movement. To accommodate the front sight's full range of motion on my Hammershot, I had to remove a separator between the rail sections. Be aware that you may not be able to clip the sight over the rail without damaging it. To achieve bright dots on a black background, use a filament change script to switch from a black filament for the main body to a more visible color like white, yellow, or orange for the dot. Place the model on the print bed with the dot facing up so that it's the last thing printed. Once you've sliced the model at your preferred resolution, determine the first layer where the dot is isolated and change filament there. The script I used to change filament on my Prusa MK2S came from this page: https://www.thingiverse.com/groups/simplify3d/topic:10525
