Greco V2 public print-pickup package

Recommended order:
1. Optional shorter risk check: open greco-planter-v2-quick-cuff-guide.html and reslice greco-planter-v2-quick-cuff.stl.
2. Full planter: open greco-planter-v2-print-guide.html and reslice greco-planter-v2-print.stl.
3. Review evidence sheets before printing.

Caveats:
- No physical print was performed.
- The quick cuff contains no printer-ready G-code; reslice it.
- Full print estimates vary by printer, material, and slicer profile.
- Mesh watertightness is geometry validity, not a sealed-vessel claim.
