This a simple sling. Be carefull it can really injure someone! You are totally responsible for what you do with it. Instructions Download the STL file, you can print it as is if your printing bed allows you a size of 18cm.I printed it with an infill of 10% grid hexagonal(no rotation angle) Layer thickness 0,5, PLA, 2 extra shells. You can use the DXF file to cut out the rubber part from an old inner tube from a bicycle or a car. The rubber part on the DXF is about 40cm long. It works perfect and it's rather strong. Shooting pieces of wet toilet paper is fun and messy!
