High-strength Nunchakus

Facing fans of nunchakus, I designed this high-strength nunchakus, which greatly enhances its strength by placing all the force directions on the XY plane.Please note the following points:1. The filling rate of the chain must be 100%, and the filling pattern must be concentric.2. The weight of the stick can be changed by adjusting the filling rate of the stick.3. The size accuracy of each printer is different. If the chain pin is loose, it can be fixed with glue.4. If you are not proficient in using it, you can purchase a sponge cover for the handlebars of an electric bicycle, install it on a stick, or use other soft materials to tie it to the stick to make it soft.5. Due to material limitations, please do not use chains to strike hard objects. Although the chain has a 100% filling rate, it will still break.6. The stick is relatively long, and if you use materials with high shrinkage, it may deform during the printing process. The sides of the stick may lift off the printing board. Ple
