Medium-sized lightweight bookend inspired by xyzaxis's Lightweight Bookend (Thingiverse).
Simple, low-filament usage.
The lower end 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; clip it off after printing. Suggest using a high-adhesion bed like PEI.
