 The [IBM Selectric typewriter](https://www.ibm.com/ibm/history/ibm100/us/en/icons/selectric/) uses an instantly-recognizable "ball" of type instead of a fanned-out array of arms like a conventional typewriter. These typeballs could be swapped out, meaning you could easily write documents with different fonts, font sizes, special characters, or different writing systems altogether.
 
 IBM and some other vendors made lots of different typeballs, but most of them are 40-50 years old and no one has been making new typeballs for a long time. 3D printing is a natural fit for making new typeballs, but most printers still don't have the ability to produce the sharp details necessary on a sufficiently-resilient material. So it's understandable that no one tried to make a really polished 3D-printable typeball. Until now, that is!

 1. Open `oneletter.scad` and change lines 10 and 11, the ones that specify the font height (in millimeters) and the font name/style for OpenSCAD to use.
 1. Open `selectric_generator.py` and change line 5, the one that says `PATH TO OPENSCAD = r"{something}"` so that it points to your installation of `openscad.com` (not `openscad.exe`! They are in the same folder probably, but the `.com` is meant to be run from command line, which is what we'll be doing.
-1. If you want to change the keyboard layout, edit `uppercase.txt` and `lowercase.txt`. Right now the way they are set up is a little...strange. I need to adjust that, I have some ideas!
+1. If you want to change the keyboard layout, edit `uppercase.txt` and `lowercase.txt`. Each .txt file has four rows, representing the characters in order on the Selectric keyboard. For example, for a standard QWERTY keyboard layout the files should look like:
+```
+uppercase.txt
+!@#$%¢&*()_+
+QWERTYUIOP¼
+ASDFGHJKL:"
+ZXCVBNM,.?
+```
+```
+lowercase.txt
+1234567890-=
+qwertyuiop½
+asdfghjkl;'
+zxcvbnm,./
+```
 1. Run `selectric_generator.py`. On my machine, each character takes between 1 and 30 seconds to generate, depending on their complexity. So 88 characters will take a while, be patient!

+How do you set the horizontal spacing between keypresses on a Selectric? There's got to be a way, right? Knowing the exact horizontal advance between keystrokes is critical if I'm going to get a Mongolian typeball to work. That would also require me to acquire a right-to-left writing typewriter; can all Selectrics change writing direction?

+Other right-to-left scripts to try: Thaana, N'ko
