Just in case anybody hasn't been following hobby/low end industrial 3d printing recently; it's come a long way.
I've been lucky enough to start a company making (and soon to be selling) 3d printers, and as such, get to make/print a pile of stuff for testing and for fun.
I used to do a lot of Nerf stuff with HvZ, so I decided to design a printable blaster from scratch for funzies. It just happens to be a good example of what a 3D printer that costs under 3K can do. The material is around $1 per in^3 so making custom parts is a lot more feasible than it once was.
The whole gun took about 13hrs of print time, but only $10 in plastic. The springs I had laying around the house. I think the primary spring is from an old night-finder but I'm really not sure. It gets about 1.5x the distance of a lightly modded maverick. It was designed for a fun proof of concept to be built upon upon, not for performance.
Everything plastic was printed on a Fablicator except for the PVC cylinder. It is all ABS except for the catch, which is PLA. The designs will be uploaded to thingiverse once some last minute changes are finalized.
The whole thing is every bit as rigid as an off the shelf Nerf blaster, if not more so.
Shameless plug; The website for the 3d printer I designed is www.fablicator.com (still under light construction)
