MegaXL Spigot SCAR

The MegaXL Spigot SCAR (or Silly Scar) is a SCAR attachment for 16mm OD aluminum Nerf hobby barrels that stabilizes darts, is easy to attach and detach, is fully air-sealed, and it allows you to fire MegaXL darts off the end of your blaster! 

The scar has three parts to it: The SCAR barrel itself, a locking nut used to tighten it to the barrel, and an 016 o-ring that goes around the barrel. This o-ring is what the SCAR nut tightens against.

If you don't have an 016 o-ring, a rubber band can be used as a replacement to keep the SCAR in place. The rubber band will not provide the air seal to the SCAR, but that isn't necessary for it to function at a basic level.

There is also a part called BarrelCap, which is basically just something to put over your muzzle so you don't core-sample someone with your sharp metal barrel. It connects to the barrel the same way as the normal SCAR.

MegaXL Spigot SCAR Print Settings

Print all of the SCAR at 5 walls 20% infill. The threaded end of the SCAR faces the build plate. No supports are necessary, but a brim might be needed to print smoothly.

Make sure the Z-Seam is straight down one side of the SCAR. Otherwise, it might not launch MegaXL as nicely, and it looks bad with misaligned Z-Seams.
