This version of the Jian has a screw on cap so the blades can be printed separately then inserted or replaced.
Supports are not required, for best results use a .4mm nozzle. You can print the blades all at once concentrically or one at a time in vase mode. I suggest printing in vase mode but if printing concentrically, the test print can be found here. Find detailed instructions on how to print collapsing swords on my website. I achieved the color changes with a single extruder printer with a couple manual filament swaps.
