This design generates a rectangular, open‑top box with four honeycomb‑patterned walls and an optional honeycomb or solid bottom. 

The design is single‑file (no external dependencies): all honeycomb generators are included (`hex`, `hex1`, `hex2`, `hexp`).

- Fully Parametric: independent length × width × height (`length`, `width`, `height`), wall thickness, frame width, and hole size.
- Manufacturing‑Ready: Walls and (optional) bottom sit flush on Z=0; bottom uses true through‑holes (no thin skins), and fits inside the walls to avoid double‑stacked frames.
- Strength & Ventilation: Solid frames around the honeycomb improve rigidity while keeping weight and material usage low.
- Use Cases: Ventilated enclosures, lightweight bins, desk organizers, decorative boxes.
