This is an eskrima (escrima) stick you can print out and practice with. With 6 shells and 30% infill, the weight and feel will match a real rattan stick, but unfortunately, it will break after a few really hard hits. This is great for practicing forms, but probably not ideal for sparring. Blog entry on my first attempt: http://theamazingdoctorawesome.blogspot.com/2014/03/3d-printing-eskrima-stick.htmlPrint out each end cap and twelve nodes using 6 shells and 30% infill. If the fit is too tight or too loose, you can use some sandpaper, or adjust the "wiggle room" in the Eskrima_Stick.scad file. Glue the pieces together using acetone (assuming you print with ABS) and let it set. The weakest point of this design is actually not where you glued it together, but in-between the connections, where there is nothing but 30% infill pattern. Higher infill percentages will be tougher, but they will be too heavy and lose the natural feel of a real eskrima stick.
