But that time has not yet arrived because the numbers need to be put in
a circle around the wheel. First the circle needs to be added so that the
numbers will be curved around.

There is a significant difference between curves and meshes.
With a mesh any curve perceived is the result of having a lot of
straight lines in a small space, but zoom in close enough and the
illusion is broken. With curves on the other hand the lines are
mathematically defined, and thus remain smooth at all zoom
levels. Curves can be used to do modeling if a curve surface is
calculated, but curve modeling cannot take advantage of many
modifiers, such as Boolean that make modeling easier without
first being converted into a mesh. Additionally when exported
to an STL some resolution will have to be decided on since STLs
do not use curves.
