I wanted to put books into my gridfinity shelf... but there were no gridfinity book holders that I could find. That's why I created: This Gridfinity Book Holder. The params You can print it and it holds your books in your gridfinity shelf. Is the full size book holder is too wide for your book? No worries - I also created models where I scaled down the book size by 4mm each iteration. That way you can print out more of them and swap them out when you read new books :)! You can figure out how big the book holder you wanna print by measuring your book and choosing the next bigger size (unless your book is really squishy, then you could go for smaller size aswell). The hardware Printed on Bambu Lab A1 Mini Any filament Can use 6x2mm magnets if you have magnetized gridfinity bases
