Then she will indeed open it.  What does she see inside?

Printing presses, several of them, and racks of type, and a person whittling away at a letter. "Hello there!"

"Hello, hello.  You must be the printer, then?"

"One of them, have you got something you want run off a few times?"

"Not exactly, no; my cohabitor is interested in how the presses and the type get made.  Thinks that printers might have the skillset to build some of the projects she's working on realizing, and that if you don't, you'd know who would.  ...Also, she thinks you could save a lot of effort by troporting the malleability of clay onto your chosen blank and then, funnily enough, pressing it into a mold taken of your type.  Instead of whittling individual pieces each time you need another."

"Well, we're open all sands if she wants to come by when she wakes up and talk to my co-worker."

"She's listening right now, as it happens; I'm just keeping her on task instead of wandering off into a research paper on the sociological and economic implications - and presumed cultural effects - of adults not ever sleeping, compared to back home.  For example.

"She's very distractible."

"- she's listening? I don't think I understand."

"She's awake, for most values of awake; she's just presently not holding the metaphorical reins.  ...Maybe we should print up an explainer.  We'd just need some time to develop the actual text.  ...And, presumably, funds," she sighs.  "We don't exactly have amounts of local money worth mentioning, at the moment."  (Though it's not like she stopped picking up loose change.)

"Well, I'm not super busy right now, all the drying racks are covered in pages and I won't start the next batch till there's space for them, if you want to ask - her - questions now."

"It's more that she has plans, and wants to share them with someone who might find them interesting.  Keeping time with a single glass of sand is...rather prone to human failure, and she has just spent the last sand or so figuring out a tentative design for taking humans flipping an 'hour'glass - excuse me.  Second language problems.  She has just spent the last sand or so figuring out the design for a longer-functioning mechanical timekeeper, and does so want to go on about it."

"I don't really have any expertise in timekeeping, I'm more here in my capacity as a carver."

"Do you know what there is on the market, if it's not just...

"Hourglasses all the way down, she says to say, making a literary reference that it's quite likely no-one on this plane will get, because she's very herself.

"But honestly, we're certainly interested in the whittling; we've had quite a few ideas for how to replicate arbitrary single parts, but very few ideas as regards making parts to begin with.

"If only we had a set of encyclopedias from home on hand.  Then we'd actually have any clue what a lathe is, and why it's such an important machine slash tool for 'industrializing' - I mean, building better tools.

"...Should check the dictionary later."

"...I don't think I'm a good person to talk to about this."

"Sure.  We weren't expecting you to.  Do you know who would be?  If anyone is."

"...honestly it sounded to me like you were having more fun talking to your cohabitor than you would talking to anyone else."

"...You're not wrong, but the problem is that our dreams will only ever be just that, if we can't actually organize the making of them.

"And to do that, we're going to need people, or at the very least stuff."

"So you're looking for... people... to give you stuff?"

"That's...not a totally wrong impression, even if it misses most of the nuance that my counterpart would insist upon.  I'm looking for -

"No, A- Mira, I am not quoting Archimedes at the print shop guy, that saying doesn't even make sense on an infinite plane!

"...Oh fine.

"We're looking for a metaphorical lever and a place to stand, with which to move the world."

"I think maybe you should take her suggestions less," volunteers the print shop person.

"I was, unfortunately, outvoted on that matter by local appreciators of dramatics.  But seriously, what we're looking for is...well, leverage.  We can't - or at least don't know how to - set up shop somewhere and start building things.  ...We're rather foreign, if you haven't noticed."

"Oh, uh, I did notice. I've never met anyone half so foreign."

"We're a bit of an odd duck even back home," she just a bit forcedly laughs off the awkward, "so it might be a little of that, too.

"Anyway.  If you're interested in cutting down on your type-whittling needs, we still do have that idea."

"I'm not, really, since that's what they hired me for and if they stopped doing it this way I'd have to find a new job."

"...That does make sense, but uh.  I don't think that innovation's going to not-happen unless your opinion is shared by all the print shops here."
