I am really glad that there are many guys like this collapsible katana, and I do appreciate your suggestions and opinions.

So I found some time and made a new one, addressing the following issues in the old one.

1. The strength of the handle-guard connector. This time I combined the handle and connector together to enforce the strength.
2. The decoration on the handle is better to be multi colorred. So I made a new structure with the outer shell and inner shell to form the handle. With different colors of the shell, the handle now looks more real.
3. The blade guide is thicken so should not be easy to break now.
4. the disassemble structure are located at the tail now. And now only two pieces of filament could lock it.

Some important suggestion and notes

1. When printing the slide lock, I suggest to use the Cool/Smooth Plate. As when using Textured Plate, the thickness of slider sole is a little bit thicker than it should be, it might cause hard to slide.
2. Still need to use a little bit instant glue for the handle and guard, do not apply too much as it might glue the slider too. Don's ask why I know it :)
3. The holes to lock the tail and handle are printed without any support, so it might not be perfect. This might cause the filament hard to insert. I suggest to use a Hex Key 1.5 to clear the holes first.
4. The folding diameter of the rubber ring is 60 mm.
5. This time, the handle is printed with Support, and I have tuned it many times to perfect the rhombic holes. BUT it is still not perfect.

If some one has better ideas, please let me know, or update your configuration here.
