A simple and modular design to hold your wrap boxes under the shelf.

Contrary to other designs I have found online, I wanted this to use as few filaments as necessary.

Also, I wanted to be able to put as many as I wished next to each other or to split them easily.

Simply print 2 hooks per box and stick them under the shelf with some double-sided tape, one behind the other with enough room between them to hold the box correctly.
There is a little dent on the top to put the double-sided tape so there won't be a big gap between your shelf and the holder.
