"Standard estimates for indoor PETG longevity are 10–20+ years under normal conditions, with some sources giving a more conservative 5–10 years. A century is 5–10x beyond those estimates under passive conditions." Wow! Thanks for pointing this out. This is fascinating.
You could even get a binder, and then print the QR codes sheets as 'pages'. You could print these thin enough to do 1mm sheets. That means ~ 120 of these in a 5 inch binder. So, a 3 ring binder of 1mm sheets of 177x177 QR codes would hold about 346.2 KiB. You could store encryption keys in this way. You can probably push the density well past 177x177 even on a Mk4s pretty safely. I may try this later today.
There are woodworkers on YouTube who use CNC, some who use the best Festool stuff but nothing that moves on its own, and some who only use handtools. Where is the line at which woodworking is not their craft?
