This is basic design #2 for a NERF barrel extension. There is a ring mount that lets you connect it to some NERF weapons and a shrouded 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 am currently printing this design on my MakerSpace's SoliDoodle3 pinter.

Improvements over previous designs:

• The portion of the barrel that inserts into the blaster is deeper and of slighter narrower diameter to hopefully fit better
• Increased bore diameter
• Extended shroud several mm to protect hand from burning on hot barrel
• Moved iron sight lower on the barrel for improved looks.

Use care and do not force insertion!
The 165mm length barrel is the maximum height that will print in an 8 inch vertical printer while the 147mm length barrel prints in a 6 inch vertical.
