Summary

After using simple 1/2 inch PVC conduit as blowguns in a Nerf war, I figured I could print up a revolver to increase my firing rate. Designed for Nerf N-Strike darts (up to 80mm length, 15mm diameter), this revolver fits six darts and can fire them one after the other (it's a blowgun, for simplicity and accuracy).

It's designed to fit snugly onto a nominal 1/2-inch PVC conduit pipe (21mm OD, 3mm wall thickness), and uses 10 4x1.5mm neodymium disc magnets to lock the chambers into alignment.

Known issues

  • If the end piece is printed airtight, when firing, some air may leak into the adjacent dart chambers and cause them to blow out of the chamber towards you.
  • The tolerances on the parts cause air to leak out in general, reducing the effective range of the weapon. Could possibly be improved by adding O-rings.

Instructions

Print all four parts. Glue the magnets into the holes in the chamber and end pieces (taking care to orient them properly so that the chamber and end pieces attract when put together).

Use 8 of the M3 screws you have left over from your Makerbot (or any screws about that size will do) to fasten the mouth, cover, and end pieces together, and use 2 more to loosely hold the chamber piece in. The chamber should rotate freely and then magnetically lock into position.

Cut a length of 1/2 inch PVC conduit (2-3 feet works pretty well). You can put a coupler in the middle to allow easy storage, plus it converts into two short blowguns in a pinch.

Although using a PVC wye would be cheaper and easier get, you could put a tac rail on this thing and make it even more awesome that it already is.

Awesome - and thous the arms race begins. like we needed reasons not to work, this is like a required print for office wars, next print your own WMD's ?

WOW!
I am SO finishing my miniature pipe-crimping valve, then I can attach this to my air compressor.

This is da bomb!!! Now i gotta figure out how to attach this to my iPhone revolver :)

Ok, that is awesome! Hope you make some news with this one!
