Kiếm Tí Hon (Thu Gọn)

This is my silliest design yet, but fun to play with anyways :-)

It is a collapsible sword (or lightsaber, or magic wand), that is small enough to fit in a pocket.

After printing, inset the 5 parts of the blade into the hilt and close it with cap from a normal PET bottle. The cap prevents the blades from falling out. If you wish, you can use a second bottle cap to close the other side of the hilt. This prevents the blades from extending and makes it convenient to bring the sword with you (e.g. in a backpack).

I tested the sword with different caps from PET bottles available where I live, but don’t know if all the bottles internationally use the same cap designs. If your caps don’t fit or if you don’t have any available, I also included a STL so you can print compatible caps yourself.

Print Setting recommendations:

• Layer height: 0.25mm (don’t bother printing smaller as you won’t really notice a difference in detail)
• Perimeters: 2
• Solid top/bottom layers: 4
• Infill: 15% (only matters for the hilt of the sword)
• Support: no
• Brim: Outer brim recommended for adhesion
   

Post Processing:

Make sure to cut or file away the brim or elephant foot nicely. This makes it easier for the blades to collapse.
