Tanjiro's 1st Collapsing Katana (Patreon)

There are five version of this sword:

• Print-in-Place Single Color

• Print-in-Place Multi-Color (requires a MMU, AMS, IDEX, or Toolchanger)

• Replaceable Blade Single Color

• Replaceable Blade Multi-Color (requires a MMU, AMS, IDEX, or Toolchanger)

• Replaceable Blade Single Extruder Multi-Part

If you print the single extruder multi-color version be aware that the wrap has a stepper then typical overhang.  You will need to print it slow at a low layer height, I printed it a .15mm. The two black pieces on the guard trap the red part to the yellow.

I achieved multiple colors with the single color versions with manual filament swaps.  

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.
