Stackable Pencil Bin – 2×4 MultiBoard Unit

This stackable pencil/pen bin is built on the MultiBoard/MultiBin shell system, scaled to a 2×4 unit footprint.
It features simplified bottom connectors for easy classroom stacking and improved durability, plus a hex-grid wall texture that makes contents visible from the outside.

Perfect for organizing pencils, markers, or tools in a modular setup.

Printability Notes

• Bridging: If bridging across hex openings sags, reduce bridge speed to 20–25 mm/s and set bridge flow to ~0.95–1.0.
• Stack Fit: If bins are too snug, apply Horizontal Expansion of −0.05 to −0.15 mm in slicer.
• Material Choice:
  • PLA: crisp detail, easiest tolerances, great for indoor use
  • PETG: more durable, good for bins that are handled often
