Everybody...Didn't ask for alternatives to using paper.
Asked for "best method of paper spheres" at that small scale. PPino...I think thats just too small to use the common methods of making a sphere out of paper. Even as few as 2 or 3 parts to do each hemisphere, would be incredibly difficult without using some very lightweight paper. If you could find and handle such paper, then you might try the "dome" approach using a ringed section and then capped with two part (half circle) upper section. Like I used on my radomes. .... Doug's first sphere approach worked, but only because of the internal form. A purely paper hemisphere might be easily constructed using the "snub dodecahedron" ...as suggested by Doug also. http://www.korthalsaltes.com/model.php?name_en=snub%20dodecahedron Assembling two hemispheres would simplify the task a little, and you could smooth out, and round the paper hemisphere once it was glued, and before you attach the two halves.

you can also press mold some wet paper by pushing a bead or marble the size you require against the wet paper, into Styrofoam. let it dry and coat with glue. do another, cut in half and white glue them together, that should satisfy your needs.

Hello paperpino,
there are three methods for making spheres out of paper: 1) with cones (HERE) 2) with segments of cutted of the zylinder hull (HERE) 3) the zarkow method, it is a fruit rind, nevertheless it works also: see pics

Take a look at the spheres Uhu02 includes in his Aquarius models. There's a number of different sizes, all in the neighborhood of 2-3cm diameter. It's pretty easy to pull the shape out of his design (i.e. remove texturing) using Inkscape. They are all 5-7 piece stacked conic sections, like the one shown on Dave's Herky radome.

that rind is pretty cool I have never seen that before!

Hi Pino,
a few months ago I re-worked n8s' BB-8 figure. I find the design of the body ball pretty effective, the result looks nice and clean and it rolls EXTREMELY fast. Maybe the template gives you some inspiration: BB-8 papercraft by Revell-Fan on DeviantArt BB-8 revised paper model by Revell-Fan on DeviantArt |

Perhaps the Mechwarrior Osiris has taken some ideas from Lockheed:

Thank you for your suggestions, very precious...
Some of them require a skill that I unfortunately do not have. After many experiments I realized that for a sphere with 3-4 cm diameter, the classical development with twelve half gores per hemisphere is good enough for my purposes (an automaton). The cutting plotter is in this case very useful to assure the needed precision. See the result:

Nice looking sphere.
It should roll around quite nicely.

I don't believe a more elegant solution could have been found. Classic!
