Brass Knuckles

I have small hands for a man. Every pair of brass knuckles I have ever put on have spread my fingers out to wide. I designed these knuckles to fit myself. For context I wear medium size latex gloves. My original design started at 21mm hole size. I ended up scaling up the CAD file myself. I didn't measure but I am guessing the hole sizes in this print are 25mm to 26mm. That being said, you can easily scale these up to fit yourself.
