could be much more than just improving it
only use original chassis, magnet system, and voice coil, and change the rest

this is what i have in my mind for a long time, but it's so rarely mentioned on the web, compared to other audio related activities - i can't find any info on making cones, surrounds, spiders .. just generic commercial recone-stuff. i know i have to learn mostly by myself, but i appreciate anything i find (like this thread, even if it lacks basic since people here are experienced). thanks again and sorry for off-topic.

They can be designed for low spring rate in the axial direction, which is nice for getting your desired Fs. At the same time, they can also have high spring rate in the radial direction, which is great for centering. Finally, they have no stiction which is a problem in slide-type assemblies (e.g. Adire Audio Parthenon).

a folded piece of paper works fine for a small fullrange cone, and is very well proven too

Those spider arrangements look like they create non-linearities from the slippage (which needs the static friction to be broken free first).

EDIT: You should remove those sharp contours. They are stress risers.

I like the fact that the areal is small this will produce less sound and interfere less with the sound that the is cone making. I am still confused to what kind of spider I will be using, I need a very soft one due to the low cone mass.

Here is a picture of my new wizzer, the weight is a bit under 100 micro grams, in fact I can't measure it on my scale sense the resolution is 0,1 gram.

Take care
Of course what i presented are just conceptual renderings. Im discussing the material and 3D printer limitations with the people operating that machinery in order to get what i want.
