Customizable Pushpin Shuriken

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.

Update: now works with customizer for custom creations. As many pins as you want, as big as your printer can handle...
