matchstick gun

thingiverse

This powerful tool is designed for daily office use and can be used in many situations to help resolve conflicts, administer punishment, or simply exact revenge. How it works: Check out this video: https://www.dropbox.com/s/tisqgm1mumcrdu0/firing_90_480p.mp4?dl=0 The lower part's handle warps easily, so it's recommended to use a heated print bed. Attach the upper part to the lower part as shown in the picture with the black gun. Mount the sides of the handle and the spring from the clothespin as illustrated. If necessary, fill the handle with something heavy like lead fishing weights. Pull the sled fully backward and forward, insert a match, and then pull the trigger. There is an optional challenge: equip the gun with a ballpoint pen spring to make the sled automatically return to its resting position. However, this requires breaking off the flexible tongue above the barrel of the lower part. Mount the spring in the small void between the rear end of the lower part and the 5mm inset on the upper part - this step can be quite challenging. Note: This device is not harmless, so don't shoot at anything living. I've also included a SketchUp file for anyone who needs to make adjustments or create a remix. Enjoy!
