In some cases I like to stack books.
And these stacks keep on growing.
In order to reinforce them, I wanted to have a bookend that grows together with the stacks.
You will need one foot part, one top part, and as many stacker parts as you want.
Protip: you might want to reduce the thickness of the bottom part of the footer in the slicer by cutting a few mm away. Or not. I was undecided.
Protip 2: for the look in the pics, I used fuzzy skin settings on outside walls: 0.3mm distance, 0.2mm strength/thickness. (Do not add fuzzy skin on the top part of the stacker, so you don't risk it not fitting into the whole of the next stacker or the top part anymore.)
