Q Tip Cannon

thingiverse

This is a nifty little device to shoot Q Tips, matches, or pretty much anything that will fit in it. All you need to do is take the spring out of a clothes pin and attach it as shown in the picture. Then, if using Q Tips, cut one end off and put the cut end in the cannon to provide a smooth transition out of the barrel. The stronger the spring that you attach, the more powerful it will be. Also, thicker springs work much better, as there is a bigger surface area to hit the end of the Q Tip.
