The Midwest RepRap Festival isn’t just people hanging out with their 3D printers all weekend; There are also people bringing all the things they made with their 3D printers. There was an R2D2 and half of a B1 Battle Droid, a 3D printed quadcopter and of course 3D printed weaponry. [Ryan] and [Kane] from Mostly Harmless Arms brought a collection of their totally not trademark infringing not-Nerf guns.
The guys have a few designs for guns that shoot silicone-tipped extruded foam darts much further than a Nerf gun. There’s a bow, a more traditional spring-powered blaster, and a crossbow. All the designs with the exception of a few pipes and tubes and springs are 3D printed, and all the parts are small enough to fit on an 8″ bed. The darts are made with a dome mold for silicon and insulation foam that’s normally wedged in window and door frames. They’re dusted with cornstarch to prevent sticking, although in the video below there were a few jams. That’s to be expected; there was a camera around.

I’m not sure if they have updated it, but it plays fine for me at the time I’m writing this.
“Mostly harmless Arms” that has to be a hitchhikers guide to the galaxy reference, right?
I LOL’d right at the end when Brian manages to hit the camera lens. I’m don’t own any NERF guns or 3D printers but this one makes me interested in acquiring both.
Wow!!! A gun post with only 5 responses? Haven’t seen that in a while..
