Literately. How difficult is it to make the design files? I'm unfamiliar with the program. For example, a magstrike clip?
What really excites me is that the possibilities are ENDLESS.

and given incentive, i might also make custom, possibly rearloading magstrike clips that accept a barrel type of buyer's choice, hehe.

Also, the possibilities are VERY limited. These machines rarely have very good resolution, so some post-processing (whether machining, sanding, etc.) is necessary for close fits. The parts are directional; they probably are weaker in a direction perpendicular to the layers. Some parts will be distorted for any number of reasons (I had this problem when I used FDM). The material is only some sort of plastic. Most FDM machines use ABS, but some can use PC.
Certainly FDM opens up some possibilities. But these possibilities are available to everyone as there are online businesses that will make RPed parts for people. Of course, you'll have to pay the real rate for those services, as this is the real world.

It's pretty awesome you are allowed to churn out kits at what seems like a reasonable price.
The stereolithography machine I used to manufacture the BS-8 and BS-9 magwells ran about $100 per hour of build time. Those 2 parts took about 8-10 hours a piece to complete so if I didn't have unlimited access to the machine then they would have cost around $1000 each. Far out of the question for a Nerf gun.
My experience with FDM never created parts that were worthy of actual use. The SLA and SLS methods both produced parts that were much more homogeneous and fit for actual use....but they cost much more mainly due to laser time rather than material cost.

A suggestion I have, for at least non load bearing components (like the handle, and possibly shells), would be to try out a stereo lithography machine. I used one of these during a design challenge I took part in (F1 in schools, if anyone has heard of it), and small components are relatively cheap, on the order of 30RMB, or around $5 a piece. The main drawback is that most stereo lithography processes produce fairly weak components. Also, the 30RMB components we made were fairly small and thin, so prices for bulkier, stronger components probably would cost around $15 or so.
Of course this only applies to those who don't have unlimited access to a 3D printer, but I can see most of a blaster being built out of stereo lithography processes, with only major load bearing parts (like the catch plate) being made of some stronger material, e.g. polycarbonate or aluminum. If your in select parts of Asia (mostly China) a company called Lanxum (I've included their English site) rents out stereo lithography machines for fairly reasonable prices.
I beg to differ

If you could design slightly smaller parts and used cheap ABS (~$40 per pound) on a hobby printer like the makerbot you could probably make this economical. Maybe not for a kit business, but I'd pay a premium for a custom built nerf gun. The potential for innovation is more important to me though. Sick of having all nerf guns designed in confusing and modder unfriendly ways? This is one cure. There's already people in the comments talking about making it modular or double barreled, so I wouldn't be surprised if a derivative was uploaded soon.
