About this deal

Alrighty now for the real deal. I've mentioned before that the design I got made was the first version of the one pictured in stage 2. This version had a slimmer rotating portion. The rest of the gun I've designed based on different guns. The length and design of the gun was based off of the guns in the movie Equilbirium. The handle I made so that it could fit the Beretta 92 side grip panel. For those who don't know what Pepakura is, it's a software which converts your 3D object into flat pieces with tabs so that you could make it out of paper or anything flat. You can get more info on how to use the software with my previous instructable "For Halloween... Why Not be Yourself?" Another handy little feature that this program has is that it could export the cutout pieces into vector format, which is the eventual outcome we are going for. My design is based off of one of Over Boost!?'s design... don't remember which... I'll try to explain it as best as I can...

So what to do from here? Open the exported EPS file you got from Pepakura and organize them into the Ponoko template. For other places I'm going to guess that you could make the document the size of the material you got and then organize the pieces on there. Next measurements. Measure out your hand so that you could design the gun so that it fits your hand. Then you could measure out how long you want the gun to be. Make sure that the rubber band you plan on working with are able to stretch long enough so that it could fit the gun without breaking. Next is the actual design portion. This is often the hardest part of the whole process, I've even heard that rubber band gun designing can be even more difficult than actual gun designing. The first images shows the innards of the rubber band gun. Notice how the rotating part with the teeth has gray goop over it and a tooth missing? Yea that's my attempt at fixing it and trying to get it more rigid with some epoxy and thin metal rods. The second image is a close up.Some suggestions for organizing the pieces. Try and get some of the pieces to share an edge to decrease cutting time. Make sure you don't have double lines, this could lead to the laser going over the spot again, which could widen the cut patch, making the pieces not as accurate as they're supposed to be.

Now depending on the service you are using, they may ask for different file formats, but these are usually a vector file format like AI, EPS, or DWG. For the service I use, Ponoko, they have AI files that has all the settings and the sizes of their sheets. You may wonder why I sent the first version in and not the second, well... I had made and sent the designs before making this instructable. By the time I had looked it over and saw my design flaws it was too late. Now all that's left is to save up my money and make the second version later on in life. The third images shows what I tried to do to fix the teeth so that they stayed rigid, but... yea didn't work out too well, gonna go out tomorrow and get myself a metal sheet, cut out two copies of the part and somehow attach them to the sides, making them more rigid... hope that works.
