I made this to use the vertical space I have on my bookshelf. You can put books on top and some other small things underneath the shelf. You can place them on a row to make it longer. I made this to fit on a 220 × 220 mm printer bed. 

IMPORTANT

**The normal STL file don't have the honeycomb mesh pattern on top, it just has a flat surface. I added the mesh pattern in Orca Slicer as a modifier. Just added a modifier cube to that area and changed settings for that area like this:

• Wall loops: 0 (This removes the outer perimeters).

• Top shell layers: 0 (This removes the top flat solid layers).

• Bottom shell layers: 0 (This removes the bottom flat solid layers).

• Sparse infill density: Adjust to your preference (e.g., 15% or 20%).

• Sparse infill pattern: Honeycomb
