Collapsing Buster Sword Replaceable Blade Version

This collapsing buster sword has threaded rivets which allows you to print the blades separately and assemble them after printing. The outer four rivets thread into the last blade segment trapping it in the guard.

The handle glues onto the guard. To increase the strength of the handle and the connection between it and the guard, a steel rod 6mm in diameter by 254mm(10") lg. can be used. I would suggest printing the handle with a lot of walls, and the guard with allot of top/bottom layers and infill.

The blades will print three walls thick with a .4mm nozzle. I printed mine with .25 layer heights. They are thicker than my standard blade walls for more strength. The entire sword uses roughly 1-1/4kg of filament total.

There are three ways to print the first blade depending on your printers vertical print height. If you have over 335mm in Z height you can print it in one piece. If not, there are two other options. There is a version where the tip is split into two, it will be glued together after printing. There is also a shorten version which is 248mm tall and retracts fully into the other blades. If you are having a hard time removing the rivets, I added some with slots.
