I'm working on my new project with 12cm small puppet.
My old friend is now unable to animate, sadly, so I'm making a new one which can fixable by replacing broken wire part.
I faced several problems using magnet to connect wire to tube so instead using magnet I chose micro screw and nut.
The micro screw and nut are small and short enough to achieve the shape of what I designed.
Here is the videos of progress up until making armature.
