You only design them once. However, creating an OpenScad program or Python plugin for Inkscape to make the cards would be about an afternoons work for a programmer with solid examples or documentation to work from.

This is a job begging for a custom application that goes from GUI to a CNC file in one step. Instead of coding in “machine language”, the designer could move more towards a high-level “compiled” form. Program a sequence of looped instructions to make a braid design? Import a bitmap image? Much easier!

BTW, is there a better description of how the hole relate to threads and their positions?
I counted 16 columns of 80, rather than 8 of 50.
Made me wonder if there were hole *pairs* in rows, so 8 pairs of holes represented 8 successive positions of 80 threads. Each position could take one of four values (00, 01, 10, 11)…

The whole idea behind Hollerith cards come from those. And to create those cards a special keypunch machine was needed. Now? They are a part of history, but the ones described there live on.
