I would use OpenSCAD. It's a programming language (you have to write every
object with its coordinates) for 3-D objects. You can use any text editor you
like, and it gives you a 3-D view of your model. It can export to STL (and
several other things, which I haven't used).
The good thing about OpenSCAD (for functional, as opposed to artistic, models)
is that it allows you to define functions, variables and "modules" (sub-objects
to be used zero or more times in the actual model or other modules). This
means that you can create parametric designs in it; if the next screen is a
slightly different size, you just need to change one number and you have a new
model (assuming you wrote it properly).
There are also many libraries available for it, but I don't think they help you
All 3-D printer software expects STL as input; there are many "slicers" to
convert it to a toolpath. I'm guessing there are similar options for
