Designed for the executive sized Rocketbook Fusion reusable notebook (see here: Rocketbook Fusion | Reusable & Erasable | Get Rocketbook)

I love my rocketbook, I really do - but it has sections and doesn't come with tabbed dividers. The manufacturer has recently started selling drop-in tabbed dividers for the 8.5" by 11" versions of their notebooks, but the executive size that I have (and prefer) still has no commercial solution to add tabs.

Sure you could glue or tape ad-hoc tabs to the pages, but in my experience that doesn't work well. It affects scanning the pages, it leaves a residue, and it doesn't hold well against the polymer pages.

So I created this solution (a couple years ago) and have been happy ever since.

BEHOLD: Rocketbook tabbed dividers

You might like tabs along the top edge, or maybe the outside edge, or gasp the bottom?! I hadn't thought of that so you bottom folks will have to mirror the model vertically to have your way. There simply isn't a way to upload just one STL that will cover all personal use cases. So this upload has a lot of variants built into it. Take a look at the images and you'll find legend of sorts, labelling tabs across the top from A through D and along the outer edge from 1 through 6.

I prefer my tabs along the top at positions C and D. So my 3mf provides exactly that. I also sometimes use bookmark pages with tabs sticking out on the outer edge at positions 5 and 6 so I've included those as well. The 3mf also contains objects that are supersets of all tabs and all bookmarks. These superset objects are flagged as not-printable because, well, until you split them into objects and remove the tabs you don't want they just really wouldn't be useful.

I've been using them for years and they work great. If you have a rocketbook or other notebook with a similar size and binding then this model might just be for you. I keep my rocketbook in a “capsule folio 2” from the same company and the tabs fit nicely within the padded interior, keeping the tabs safe while the whole thing bounces around in my bag.
