I was inspired by this: https://www.printables.com/model/86396-self-defense-cat but wanted to make it more robust, so I traced the shape and made my own model in pirated Solidworks. One side looks better than the other but came out well overall I think. It’s thicker and at 100% infill. Also much sharper. Would certainly hurt to get punched in the face with this… “keychain”.
EDIT: I’d be happy to share the file too if anyone wants it. I’m not sure where I could upload it but I’d be willing to try.
I can assure you, this is not a serious weapon and as I mentioned elsewhere it’s really just something small I thought would be fun to make and print.
