Before you print

Open base only; no lid or mounting posts. Walls and floor are 2.4 mm. The side opening is 12 by 8 mm, starting 8 mm above the base and 14 mm from the corner. Check bridging in your slicer. Geometry has been digitally checked; this template has not been physically test-printed.

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 spanning X=0..100, Y=0..70, Z=0..35 mm. Query current topology and remove its upward-facing top face using an inward shell named Walls, thickness 2.4 mm. Create a box named Cable opening spanning X=-5..5, Y=14..26, Z=8..16 mm. Subtract it from the shelled box and consume the tool. This forms a 12 by 8 mm opening through the X=0 wall. Keep the opening at this fixed corner offset when changing the outside dimensions. Do not add a lid, posts, vents or PCB-specific features.
