See original Customizable notebook cover for guidance on what notebook to buy and how to replace the cover.
I printed this on a BambuXL. I recommend printing out the small lego plate to ensure you print settings are such that you'll be able to attach your own lego to the cover. I also wouldn't use your most precious pieces, just in case they do fall off, but on mine they're pretty snug. I'd recommend not using matte finishes for the area with the studs, as there is higher friction and therefore more likely to pull the studs off,
Enjoy!

Added the LEGO Logo, and a matrix of studs
