AI CAD prompt: Open organizer tray

Use Nora3D native parametric CAD operations. Work in a new, named document owned by the intended user. Units are millimeters. Inspect the bound document and supported operations before writing. Use current native IDs and returned replacement IDs; do not guess face or body identifiers. Save and reopen the final model. Preserve editable feature history.

Expose only the parameters listed below. Keep all other dimensions fixed. Use English public labels and descriptions, even if the native kernel uses localized internal variable names. Do not claim a physical print, load rating, injection-molding suitability or exact recreation from the prompt alone.

Create a box named Envelope: X width 100 mm, Y depth 70 mm, Z height 25 mm, bottom center at the origin. Query current topology and identify the single upward-facing top face. Remove that face using an inward shell named Walls, thickness 2.4 mm. Keep the floor and all four side walls. Do not round corners or add a lid.
