Summary Throwing real shuriken at a corkboard will ruin it so i made these little parts that click together with corkboard pins. Should work with a darts board too, adds a touch of ninja to your darts game... Be careful, don't hurt yourself or other people. Instructions print with solid infill and press the pushpins in using pliers, they fit very tight and click into place. Inserting pins works better when the part is still warm from printing.
