Nerf Fate Shotgun Barrel

This is a 3 dart shotgun barrel swap for the Nerf Rival Fate. It should fit full length elites with the tip sticking out a bit or half lengths. I drew this up in about 15min and haven't had time to print or test it yet, performance may be lacking. It might benefit from a more restricted airflow path or looser/tighter tolerances on the barrels, depending on your printer. STEP provided for your own editing needs. This was a quick and dirty mod of EllieWhoMakes megaxl barrel swap.

UPDATE: Slightly tweaked the original barrel ID and fillets, also added chamfers to the overhanging bits in order to remove the need for supports (as suggested by a redditor). Made a shortened version intended for short darts only and a much shorter profile for easier pocketing/holstering. Modeled a 4 shot version with all the aforementioned tweaks.

I have only tested performance on the 3 shot long barrel and the 4 shot short dart versions.

 Performance was fantastic with the 3 shot, hitting the target with a tight 6-12 inch grouping at ~35ft/10m with DZ Chili darts with very little angle.  With a slight angle you can easily reach 50ft+. Standard elites were going crazy as per usual but with good speed and range.

The 4 shot short barrel is not quite the same performance but still easily hits 35ft/10m with a slight angle and slightly worse groupings. Still totally usable as a backup shotgun pistol. Perhaps the longer one will perform better?
