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. Drill for the wood screw used as a trigger pivot and turn the screw home, but leave it just a little loose for a smooth action.

Then stretch the rubber band along the entire length of your meter stick, holding the meter stick by supporting the underside of it. I first "converted" the 2D design into digital with Adobe Illustrator and used it as a template for the 3D designing. 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. To make yourself a more realistic rifle, you'll need a board about three feet (90 cm) long and six inches (15 cm) wide.

Take one end of your rubber band and catch it on the front of your wooden gun, and pull it back until you can hook it in place onto a horizontal notch. You can try adding parts to the gun to simulate the look of a real gun, like the fearsome Desert Eagle pistol. The simplest incorporate a few simple L-shaped and straight Technic™ pieces rotating on separate axles to great effect.

This program essentially scales your project to the correct size and you could then export it to a vector file format. The notch should form a wedge pointing inward on the barrel and should be thick enough to accommodate a rubber band. You'll need a board that is at least one foot (30 cm) long, six inches long (15 cm), and of decent thickness.

Using a saw or knife, cut a notch into the top of your barrel beneath where you have attached your trigger strip. Design company Weaponized T-Rex is out to bring some rapid-fire capabilities to such household conflicts, with a motorized rubber band toy based on the Gatling machine gun. Building a tiny, concealed Lego gun is the perfect way to take out an unsuspecting friend or hit someone who thinks you're unarmed in a game of Lego tag. He previously spent time at The Conversation, Mashable and The Santiago Times, earning a Masters degree in communications from Melbourne’s RMIT University along the way. That said, the Wooden Snipper Rubber Band Rifle features a 27-inch long barrel and will shoot with an accuracy of over 30 feet with the right rubber bands, and with its easy to attach scope, every shot will count.

Now that you've created a stripped-down but functional Lego gun, you have the opportunity to customize it. The 29-inch-long gun has a band stretch of over 16 inches (which means it’ll shoot accurately for over 30 feet), and even features a plastic rear sight to help with aiming.For example, a talented rubber band trick shooter might knock down a paper target or he might stun a stationary fly.

To fire your rubber band gun, aim your index finger at your target, then move your little finger away from your palm to release the rubber band.I used a construction grade plywood, so I wanted to make sure the ruff side of the plywood was on the inside of the gun on both sides. 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. Lay your pull-release string atop the barrel of your gun, guiding it with your fingers so that it lays in the tip to tip track.
