Plastic Knuckles PRO with organic ergonomics and Bonker

This is not a weapon or a toy. It is a tool for defense. Respect it as such.
Check your local laws. 
The best defense is fast legs. Avoid all confrontation.
Do your own research on how to best use this tool. 
This is not meant for kids, bad guys or people who mean to do harm.

Finger holes are made slightly oval, palm grip is thicker and more comfortable to reduce risk of injury.

There is a Bonker™ on the pinky-side of the tool. This is for applying persuasion to joints, digits and muscles.

Print PETG or PLA. 
100% infill
Print at a slight angle (one side elevated 1,5cm)
Tree supports
Model fits EU size 9-10 hand. From S-XL that is M or L. Increase scale by 3-5% for the next size up or down.

Prototype is printed in PLA, 100% infill, at an angle (one side elevated 1,5 cm). Tree supports.
Do not print at less than 100% infill unless you print for display or as a paperweight. If it breaks or splinters you will hurt yourself.
PETG is stronger. PLA is strong enough at 100% infill. 
About 5 hours to print on Ender 3v3 SE. 

Remix is more rounded, ergonomic and comfortable. Added a Bonker™
