I needed an extendable/portable stick. I couldn't find one that matches my needs so here it is:
A highly customizable telescope stick.

The following aspects can be configured:

number of segments
radius, length, wall thickness
inner/outer thread for extensions (see included ball tip example)
locking size and strength
latching size and strength
latching in retracted position
printing tolerance

Debug outputs for the resulting maximum extend and radius are given. Various assertions are included to avoid broken configurations. These may only work with OpenSCAD.

Feel free to add more extensions as remix.

Tested with OpenSCAD 2021.01.

Credits to Simon L\u00f6ffler for the helix_extrude() OpenSCAD function.
