A big shout-out to all my friends on the Creality CR10 user group forum! You guys are a huge help as always, and some folks even beta testing these designs- it helps alot!!

I hope you enjoy this great set of nunchaku, where you can choose your chain length, and your grip shape! There are round or octogonal grips, and 5, 6 & 7 link chains to choose from!

Please READ THE DESCRIPTION/PRINT SETTINGS as these can quickly become dangerous, and are still pretty painful even printed as described!

There is an assembly video and a test video of their use; but please read the below safety concerns, as well as the printing settings associated with these to avoid any weak spots in the print.

Please please please use care, discretion, caution, etc when using these.  If printed too solid, THESE ARE NO LONGER A TOY and shouldn't be treated as such.  
Bringing me to the next point:
Disclaimer:  Neither thingiverse nor the designer (me) are liable for damages or injuries caused by this design.  Please be careful!!!

The following will be reiterated below, but please: Print this with ALOT OF TOP LAYERS to avoid a weak joint where the threaded part of the body meets the thickest portion of the body. I used 5 top layers The rest has been engineered to take regular stresses in practical (non combat) use.
