[I only liked the first four books, but that's enough to cover the original story arc]

Wing is no problem as long as one can calculate how to make it stiff enough and of a right shape.
Fun fact: printing rates increased from about 120 sheets/hour to over 1 million over the course of the 19th century. Those began with wooden screw presses that differed little from Gutenberg's to cast iron, rotary, steam and later electric powered, and web (continuous paper feed) presses, and from matrix plates (with individual type set in blocks) to offset Linotype (in which the entire print block was cast as a single sheet through multiple stages from the original matrix characters).
Thought just occurs: the falling characters of the iconic Matrix screen somewhat resemble the individual type elements flowing and falling through a Linotype machine. I don't know if that is a deliberate or incidental reference, but it's an interesting one.
If I were a bit more clever, or maybe if I was 50 years older and had played with this kind of stuff growing up, I'd probably try to make a spark-gap transmitter. That seems to be in a sweet spot of not requiring too many super clever bits, and having obvious applications.
I used to have this joke(?) with my friends: remember Mark Twain's "A Connecticut Yankee in King's Arthur Court"? The titular Yankee basically upends the (faux) medieval society he gets transported to, "inventing" all sorts of technological miracles.
Well, I'm a software developer but don't come from an engineering background (I mean actual engineering, not programming). I don't even understand how electricity or the telephone work (I mean, old fashioned telephones, let alone current mobile networks). If I was transported to 2 or 3 centuries to the past, I wouldn't be able to explain modern technology to other people, let alone actually build it.
I sort of understand how steam machines work, and I could "invent" the printing press. I guess. But anything related to circuitry, electricity, chemistry, engineering of any sort, I wouldn't be able to even begin explaining them to King Arthur.
My introduction to the knights of the round table would go something like this:
"We are questing for the Holy Grail, oh noble stranger from a far away land! How can you help?"
"Depends, which version of Python are you running?"
