Party Poppers - little things that go bang when you pull the string, not the other kind of popper. Beat the New Year Party Popper Ambush with this cunning contraption that can let the paper shrapnel of nine 28mm PP\'s rip simultaneously - or go on the celebratory offensive and visit a party full of very surprised friends!Print out with a relatively low fill density - it can use a lot of plastic otherwise. Load the poppers into the flat front, letting the strings trail out the other side. When all the poppers are in place, twist the strings together so there is no slack and bind with tape, glue, shapelock or similar material that\'s good for making sure the strings won\'t slip. Point in safe direction (yeah, right) and pull the knot hard.Openscad files provided so you can change the size of the popper holes or the handle etc.I Should\'ve marked it with \"FRONT TOWARD FRIENDS\". http://en.wikipedia.org/wiki/M18A1_Claymore_Antipersonnel_Mine
