Self-Defense Keychain 3.0

A Self-defense Keychain Ensure you use 70-100% infill for optimal strength. After printing, I smoothed the surface using an iron. Parchment paper comes in handy here.^^ This model is an improved version of one of my previous designs. I have incorporated the feedback I received. Just a Info, this could be illegal to carry in some jurisdictions in the World. Check your local laws before carrying this with you. Best regards
