Collapsible Katana - Revoluted Button with Spring

This is a spring mechanism for the Collapsible Katana Sword by niltsh. This model is only the button, if you want to get the whole model, please download it from niltsh's profile.I did not have good rubber bands at home, so I designed a simple spring mechanism to bounce back the button for the Katana.
