LF1 Updated Barrels

thingiverse

Once I printed the original outer screw-in barrel, I realized the diameter of the hole was slightly too small to fit a standard NERF foam bullet. So, I made the hole very slightly bigger, so that the bullet would no longer be stuck inside the barrel when attempting to fire it. Furthermore, when I tried using Schedule 40 3/4” PVC pipe, as Landru suggested, I ran into some issues. The inner diameter of the PVC is EXACTLY the same size as the outer diameter of the piston head, so I couldn’t get it to fit inside smoothly without some EXTREME sanding/finishing. To combat this, I designed a quick inner barrel to replace the PVC pipe that will better encase the piston rod/piston head/spring assembly, and it even snaps into place very well in the gun casing. Highly recommend this, hope it helps someone!
