Hey there, wonderful people!
It's a little box that looks like a book! This one's a little larger than a gift card, and I did have that kind of thing in mind for it. Quite some time ago now I posted a gift card holder, but that one couldn't hold much more than just a card or two, and certainly didn't have fancy things like magnets to keep it closed! It also didn't look like a little book. But this one does!
The interesting thing about this model, though, is that there are two ways you might approach colouring the pages differently to the cover - discussion continues below!

Print Description
This is an articulated print, so make sure your first layer is nice and neat, and that there aren't any print issues such as stringing or overextrusion that might bind moving parts together!
The first layer is also the outer part of the book, so take care to make it nice and neat!
Multimaterial vs Single Material - Colouring the Pages!
Two versions are provided - one for multimaterial printers and one intended as a single material print. However, it's quite possible to get good results from the latter! The photos show both versions, but the single material print has had a filament change after the 3mm point so that the "pages" are coloured differently to the cover.
The main difference between that and the multimaterial version is that the single material with filament swap will also leave the hinge and latch coloured. However, it'll be much faster than a multimaterial print that needs to swap filaments on every layer!
Optional Magnets
If you want to put magnets in the latch to keep the box closed you'll need the usual 6mm x 3mm cylindrical sort. One for the cover, and one for tha pages.
Print Dimensions
The Little Notebook Box occupies 172mm x 120mm on the print bed and is 13mm tall.
Supports Needed?
Not at all! Designed for straightforward printing!
Scalability
Scaling this will work to a degree, but the hinges will get looser or tighter accordingly, and the magnet holes will scale too!
Print Orientation
The Little Notebook Box prints open, with the outer cover down, like so:
(gift card for scale!)

Further Thoughts
As multimaterial printing gets more reliable and accessible it's easy to forget how great a simple filament swap can be! In this case, it's arguably the superior option, given how much more efficient and quick it is.
Happy printing!
