Medium-sized lightweight bookend inspired by xyzaxis's Lightweight Bookend.

Similar design ideas as xyzaxis's bookend: simple, low-filament usage, thin part that goes under books.

The bottom of the vertical portion is not attached to the bottom, which removes a strain point where it would otherwise fail under heavier load.

Prints with a small brim at the skinny end to decrease the chance of peeling off the bed; use a nail-clipper to clip it off after printing. Suggest using a high-adhesion bed like PEI.
