Generates labels for organizing screws. A sample of the generated file looks like this:
The label sizes are optimized for Avery 46x11-R labels.
To rebuild, first run the python file to generate a list of screw variants into screws.dat. Then
run lualatex to generate the labels. You can edit the python file variants.py to change which screw
sizes, materials and heads are generated.
$ python3 variants.py > screws.dat
$ lualatex screws.tex
