NERF barrel extension (#1) -- basic design

This is a basic design for a NERF barrel extension. There is a ring mount that lets you connect it to some NERF weapons and a barrel with a simple iron sight on the end. The added length may increase the accuracy of your shots.
I plan on making several more designs with various greebles on them and even useful features (like rails).
As of this upload, I have ONLY printed "nerf-barrel_extension1-test1.stl" on my MakerSpace's KosselKlear Delta Printer at 330% speed for a rough test fitting
