Adjustable Bookend — Desk & Shelf Book Support (Customizable)

A clean, sturdy L-shaped bookend that keeps books, binders and records upright on a shelf or desk. The wide base tucks under the books so their weight holds it in place.

Parametric: set the height, base length and thickness for light paperbacks or heavy textbooks.

Print settings: 0.2mm layers, 3-4 walls, 20%+ infill for weight. Prints flat, no supports. PLA or PETG.

This STL is free here and stays free. The catch with a fixed STL is that you cannot actually change those dimensions — so I publish the editable OpenSCAD source for this model on Cults3D. Open it, set the numbers you need, export your own STL:
