BOSL2 can wrap 2d geometry with cylindrical_extrude and it can wrap a vnf
(vertex list and face list) around a cylinder with vnf_bend. I don’t think
you can wrap 3d geometry because it requires a nonlinear transformation to
create the wedges that form the wrapped result.
If all you want is text you should try path_text. Individual letters are
flat but the text curves with the cylinder.

I often have scenarios in which I need to wrap an element (usually text,
but others have occurred) around the side or top of a cylinder. Based on
what I have found, the only way to do this is by slicing a child into a
large number of pieces using intersection(), rotate(), and translate()
inside a for loop. This is not only inefficient, but is not unlikely
(depending on the item being wrapped) to cause areas to have holes. I have
not yet found a good library that does this, I think (considering that it
is not an uncommon task) that there should be a built-in modifier that does
this, but if anybody know of any good free libraries as an alternative I
would like to know about it. Thanks!
