Newbie question.

As far as printing fine lettering. You have to make sure your slicer is set up to print single walls with No minimum length.
If you want really fine text - use a finer nozzle.

I will give Fusion 360 Online a try, As when I tried to setup before did know have Fusion 360 yet.

"print single walls with No minimum length" and a "smaller nozzle"

I have always believed that a smaller nozzle might work better, though the the small details may just be too fine for 3D Printing with filament.

Thanks
