This modular shelf system was designed in Blender and prints entirely in PLA filament. You can choose any number of shelves during assembly. Each level uses small 3D‑printed shelf supports: insert the supports for the bottom shelf, slide the shelf down over the corner posts, and repeat for as many tiers as you need. I built mine with three shelves for comfortable hand clearance and everyday usability. A short assembly animation is included in the gallery.
