I made this for the official RVOLT cosplay entry of 2018 comicon original characters. It is scaled to a larger hand type, but reducing it to 80% scale will fit even smaller hands very well. Obviously this is not REAL brass knuckles.
Printed via the provided profile remotely so was unable to adjust any settings. The print worked and came out without any faults. But the default model is rather big. Tested with a load of people and this large side didn't fit a single person.
Recommend scaling the model down to 90/80% for better fitting results.
