Collapsible Katana

This is a collapsible Katana based on the work of 3DPRINTINGWORLD:

I redesigned it to give the blade the traditional curve that one would expect from a Katana. This is *not* designed to be printed all at once. In particular, the center blade section is in three pieces (two for the blade and one connector). My printer (Prusa Mk 2.5) only prints 200mm tall (or so) so printing the handle in multiple pieces let me make it a little longer.

Printing: All were printed using the same settings recommended by 3DPRINTINGWORLD
1. Print the blade 1-to-4 file - Stand the model on the smaller end
2. Print the blade 5-1 file - Stand the model on the smaller end
3. Print the blade 5-2 file - Stand the tip on the flat end
4. Print the blade 5 align pin file - Stand on either flat end
5. Print the handle file - Stand on the end with the smaller opening and no recess
6. Print the pommel file - Point the taper down
7. Print the guard file - Flat sid
