SorrowX's RPM-Built Nerf Blaster by MakerBlock Mar 22, 2011

Description

Disclaimer: I did not design this. Will, a commentator on my blog ( http://makerblock.com/2011/03/can-we-make-a-printed-nerf-dart-shooter/#comments ) , left a link to this page ( http://nerfhaven.com/forums/index.php?showtopic=20819 ) at Nerfhaven.com where a member named SorrowX uploaded pictures, design files, and STL's for his rapid prototyped Nerf Blaster. I've uploaded the STL's here. I suspect these parts will be way oversized to allow printing on a MakerBot. However, I'm hopeful others can build on SorrowX's excellent work.

Still working on it. Once it actually fires a dart that isn't splitting into confetti... sure :)
Solenoids are good for for this type of application, as well as compressed air. However, there is a variety of reasons your darts are shredding with it. First off, Stock darts are crap, and are no good for high-pressure applications. I recommend using homemade darts called stefans. easy and cheap to make. Second, your barrel might not be the best one for your applications. CPVC and PEX tubing are good for spring guns for their tight fit. with air, you want a looser fit of PETG found here: modmansnerfhardware.auctivacommerce.com/Barrels-C221417.aspx?sid=21391 hope that helps!
I can't wait to see your variation! Can you upload your work?

Hey there everyone, never thought I'd see this outside of a nerf forum. Addressing Mike77's challenge of making a modular version, I've already been Designing, printing and selling these things via Nerfhaven. hers a few links to some pics:

The first 2 pics show off a revolver system similar to the one you linked to, aside for the fact that it indexes for each barrel and can attach to any other modified or homebuilt nerf blaster with a 1/2" CPVC coupler.
The same attachment feature applies to the hopper clip shown in the 3rd pic.

f you guys want some more info, just drop me an email: [email protected]
Also, email me some pics if anyone else builds one!
VERY nice work. I was messing around and I think I have a variation that's worth a build. Have you had much luck with solenoids? I've tried compressed air and it seems to be shredding darts.

Looks possible to combine both thingiverse.com/thing:3249 's revolver mechanism and this. There's a scaling issue to address, and some fittings to cobble to get a good seal, but looks very do-able.

Additionally, if we make the pistol-grip a separate piece it's likely printable on any of the major printers, and I bet I can even dodge most of the support material needs to boot!

I actually own one of the guns and they function quite well.
I'll take a shot at making it modular... I've always wanted a double-barreled nerf gun.
I was looking at the video, and there's an additional small piece at the front, a small tube. I think I may keep the pistons and such, but I'm not certain why the rest is actually needed other for appearance. wonder if it might work with thingiverse.com/thing:3249 's revolver mechanism...

Well, it doesn't HAVE to print on a Makerbot. Pretty much all other printers allow way larger parts.
Very true! However, I have to admit that it ties rather nicely into my post for today about slicing large models with OpenSCAD... blog.makerbot.com/2011/03/22/openscad-model-slicer/

And, really, even if I could print it as a much larger thing, I think I'd rather it in small parts. I just like the idea of field stripping a nerf zapper into dozens of tiny partss...
The idea of being able to take a box of 4x4 pieces and assemble them, maybe along with a pvc pipe and string, to make a nerf gun makes me drool with anticipation. Having interchangeable grips, sights, etc. would be even better.
