Mesh from text doesn't always give good results usually with non-manifold headaches. I got tired of having to model letters and numbers every time I needed them, so I decided to make them all and save myself hours of unnecessary work down the road.
There are three quality levels to choose from 0 to 2 sub division levels depending on the quality you might require.
If you use them and it saves you a bit of time please considering donating, every donation is a tremendous help, and will go a long way to further my hobby, saving up for dual extruder upgrade, enclosure, other printer odds and ends, and more classes. Thank you!
If you are just going to just print the characters you might want to consider a brim, I personally don't need it with the PEI sheet I use, but it might be necessary for other printers/beds
