This is a thicker version of Anders664PI's (Awesome) Stickman Bookends (Thanks to him for posting it).

There are 2 versions, one has a cracked "wall" and the other is plain.

STEP file is included.

These should be printable without supports. Parts may not be oriented for printing.

The model in the pics was the original size, but scaled up to 130% in Cura. Even so it is a bit small at that scale. I recommend using the new scaled versions (medium or large) or even scale them up further in the slicer if you need them larger.

Update 7-12-2020: I uploaded several new models in both the plan and cracked wall versions, but scaled so there is a medium (175%) and large (200%) scaled versions now. You could scale in the slicer, but that would lose some resolution, so these versions will be cleaner. Both the medium and large versions can fit on an Ender3, but only one at a time.

Medium Versions (175% scale, about 120-130mm tall):
