ok so this is another long shot but a few years ago there was a twitter post (in japanese i think?) that had measurememts for how to make this book stand thing out of cardboard that you could use to double up books and use up more space on shelves
back then i made a bunch of these but by now i lost the pic and dont know how to find the original post anymore
if it comes down to it i can just take one apart and get the measurements from there but i would be very grateful if anyone happens to have the original post or something similar??
