I've reimagined the conventional brass knuckle with 3D printing in mind. By completely redesigning it from scratch, I've crafted a sleek and effective version that's perfectly suited for plastic fabrication. This new iteration prioritizes ergonomic comfort and robustness while deviating from the typical knuckle duster aesthetic.

Multiple sizes are available. If you're unsure of your size, there is a demo profile where you can print hollow versions using minimal filament. The actual versions, intended for full strength, are printed solid and have a satisfying weight to them.

This is obviously just a toy :)

Designing these models is HARD, and sharing them makes it harder. Creating these designs takes substantial time and effort, involving a lot of testing and a significant amount of filament wasted until the perfect design is achieved. While making models for my own use is easier, sharing them with others requires additional work. The designs need to be more foolproof and universal, and I have to create all the profiles, take pictures, and write descriptions and instructions. Your support would be greatly appreciated. Boosting my models would really help me continue sharing these designs with you. Thank you!
