Knuckle Duster - Sword Grip

I designed this to fit on my sons cardboard sword sheath. We used tape to attach it. You may need to increase or decrease the overall size. I have included the Fusion 360 design files to make that easier for you.

The knuckles are parametric. You can enter your largest finger size into the FingerHole parameter and it will resize. FingerHoleOD will add to the outside diameter.
