Nerf Knockout - Brass breech parts

thingiverse

I created these custom components to facilitate the addition of a brass breech to my Nerf Rival Knockout, as well as integrate a threaded muzzle for accessories. Additionally, I incorporated short dart storage into the design. The short dart storage necessitates shell cutting to fit properly. I've included an image demonstrating what adjustments were required. It's likely that you'll need to sand the dart holes in the holder smooth after printing. To achieve this, wrap sandpaper around a pencil and sand until your desired dart fit is achieved. Due to the tight space constraints within the blaster, there was barely enough room to squeeze three darts between the screw posts, making this compromise acceptable. Several of the brass-related 3D printed parts will require epoxy to secure them in place and provide air-tight seals. I won't be providing instructions for installing these components or the brass breech. If you're interested in learning more about modifying your Knockout, I recommend referencing WalcomS7's "hush puppy" video. The process should be similar, with some of the PVC and tape used replaced by 3D printed parts.
