3D Print Rubber Band Gun

When I first hear about 3D print event, I'm thinking of making some simple and fun toys. And then, I imagine if I can print out a gun that can be easily assembly and play with. That's the origin of what I design this rubber band gun. When I see the metal-made rubber band gun "Silver Wolf" (http://www.projectsinmetal.com/video-full-metal-rubber-band-gun/), I think I can make it as a 3D-printed version.Therefore, the major mechanism is referring "Silver Wolf". This gun can shoot 8 round of rubber bands. Each time loading the rubber bands, it is self-locked. Each time pressing the trigger, it will only shoot 1 rubber band out like the real gun. Because this gun is 3D-printed, I want to make it as simple as possibly. Therefore, I make it without any screw or metal shaft. Just slot all things in and tire with the rubber bands, then it can be played. Beside printing all parts, I've made another version of STL that make all parts into one piece. Suppose the 3D printing can do the hollow and moving parts, it can be played immediately after print! Hope I can print it out and test it :) 22/12/12 Updates: It seems there are some problem on this mechanism, therefore I've made a improved version: [3D Print] Rubber band Gun V2
