Right on. Simple text/encoded strings weren't really on my mind while imagining the more complicated solution, but you're right that data is probably best preserved with just "printing" rather than 3d printing.

I didn't have an amount in mind, I was just kind of wondering about the hobbyist aspect. Like if I woke up one day and realized I need to archive something and my most readily available tool was a 3d printer, would I have to come up with my own scheme, or has someone already done it?

That reminds me a lot of a QR code, but extended. At which point, I have to ask: Why not just use QR codes? They have the advantage of being ubiquitous, although I'm very open to the idea that they have disadvantages or leave improvements on the table.
