Fold-A-Punch keychain

I was inspired to create these brass knuckles after watching a video on TikTok. As a collector of different weapons, brass knuckles have always been my favorite. I've tried to improve upon the design as much as I can with the software I own, but I've reached my limit. The inserts are designed to hold magnets, so these brass knuckles are ready to be printed and assembled. However, I'm always looking to improve and evolve my designs, so I'm open to any suggestions or collaboration to take these brass knuckles to the next level.
