Nunchaku 30 cm / 12"

thingiverse

The Nunchaku is split in two parts for smaller printers - the two halves have registration keys for easy alignment when gluing them together. The holes for the registration keys are designed for standard 1.75 mm filament - the fit is very snugt so if the holes are too small, the filament can either be heated and stretched or some thin wire can be used - anything that fits the holes really. The smaller holes for the string are 1 cm (0.4") in diameter and will fit thin ropes, paracord, shoelaces etc. The larger hole on top is a bit wider in diameter so the string can go through multiple times for easier stringing, There's many videos on YouTube on how to string nunchakus and how to determine the right length for your hands. depending on the length of your forearm these nunchakus might be too small or too big - I think you could get away with scaling the files on the z-axis without the deformation of the holes causing any problems, since the holes themselves are fairly large. Choose your infill depending on the intended use - since I just want to learn some moves and don't plan on hitting anything I've gone for only 10%.
