3D Print Your Own Nerf Blaster For All Out Office WAR!

Nerf guns are great fun, but they're not exactly cheap things to buy in large quantities. So why not print your own?

OK, so Hasbro would probably prefer if you didn't but that hasn't stopped the team over at Mostly Harmless Arms from using some common parts and some 3D printed parts to make their own guns -- technically an Extension Spring/Latex Tubing gun, because amongst other things Nerf is a trademark.
