The standard Traveller world map is an unfolded icosahedron. If you fold it

There was a map generator at donjon.bin.sh, which could generate images
from laying the map on a sphere, or could generate Traveller-style
unfolded-icosahedron maps, but the site appears to have gone catastrophic;
perhaps it will come back soon.
