A smaller Collapsible Light Saber with twist lock blade retainer.
Easier to print, 180mm extends to 900mm
New blade design extends to a consistent length and blades can be fitted if they're not perfect.

!! Important: !! Blade models are solid and must be printed in "vase mode" or " spiralize outer contour " with a .9mm line width and no top or bottom layers. !!!

If you scale it up or down, scale the wall thickness of the blades the same percentage.

If the walls are too thick, you will have to sand/file down the inside edge of the narrow end and the outside edge of the wide end. Put the blades together backwards(both ways) to check the fit. If the walls are too thin they won't hold together.

I have only used PLA and found that filament varies greatly. some have terrible layer adhesion and the "retainer cap" would just break apart, most filaments work fine.

To assemble, put 3 retainer tabs in the retainer cap and make sure they pivot freely. Lay it flat and point the tabs inward (like in the picture). Line up the switch on the hilt with a pin on one of the tabs and jam it together. If the twist mechanism is sticky, put a little petroleum jelly in the 6 little notches on the hilt. and the top of the 3 "castles"

Retainer Cap v2 has more of a click but the file is upside-down, flip it in your slicer.
