Shelf Divider

thingiverse

I utilize one of my office shelves to keep things organized and have never found dividers that worked for me, which is why I created this solution. Like you said, it's not a traditional bookend. I believe it wouldn't be strong enough to hold a large number of books, but on my shelf, they give me nice little separations of space with room for labeling. The 'clip'/label part was designed to slide over the edge of a shelf and is sized to fit snugly on my shelf (19mm) so it doesn't move around.
