Someone requested a customizable collapsible sword - and here is my take on that topic. I decided to print a wand, but you can choose a more sword-like shape. Collapsed length, number and thickness of segments - your choice also affects expanded length and rigidity. You can also choose a minimalistic style instead of the elegant grip.

The bottom is open. Try tapping your finger against it :)

Printing: standard settings. I added some built-in micro-supports, but bed adhesion is very important.

Assembly: Well, it's a print-in-place model, so no assembly. However there are some built-in micro supports at the bottom (remove them with some side cutters etc) and inside (just break everything free).
