AI CAD prompt: Dual-port cable bulkhead adapter

Create a new owned Nora3D part document. Use millimeters, world XY as the base and +Z as height. Retain named native features and expose only the controls listed below.

1. Create **Plate**, a 100 × 66 × 6 box, centered at X=0, Y=0, with its bottom at Z=0.
2. Create **Housing**, a 72 × 42 × 24 box, centered at X=0, Y=0, with its bottom at Z=6.
3. Create **Rib left**, a 8 × 52 × 12 box, centered at X=-31, Y=0, with its bottom at Z=6.
4. Create **Rib right**, a 8 × 52 × 12 box, centered at X=31, Y=0, with its bottom at Z=6.
5. Unite **Plate**, **Housing**, **Rib left**, **Rib right** as **Bulkhead blank**. Require one connected result.
6. Create **Fastener -42 -25**, radius 2.75, height 10, initially along +Z, with its base center at (-42, -25, -1).
7. Create **Fastener -42 25**, radius 2.75, height 10, initially along +Z, with its base center at (-42, 25, -1).
8. Create **Fastener 42 -25**, radius 2.75, height 10, initially along +Z, with its base center at (42, -25, -1).
9. Create **Fastener 42 25**, radius 2.75, height 10, initially along +Z, with its base center at (42, 25, -1).
10. Create **Port left**, radius 9, height 34, initially along +Z, with its base center at (-18, 0, -1).
11. Create **Port right**, radius 7, height 34, initially along +Z, with its base center at (18, 0, -1).
12. Create **Label recess**, a 36 × 2 × 8 box, centered at X=0, Y=-21, with its bottom at Z=14.
13. Subtract **Fastener -42 -25**, **Fastener -42 25**, **Fastener 42 -25**, **Fastener 42 25**, **Port left**, **Port right**, **Label recess** from **Bulkhead blank**, consuming the tools; name the result **Cable bulkhead**.

## Public controls

| Control | Default | Range | Step | Meaning |
| --- | ---: | --- | ---: | --- |
| Left cable-port radius | 9 | 7–11 | 0.1 | Radius of the left through port. |
| Right cable-port radius | 7 | 5–9 | 0.1 | Radius of the right through port. |
| Label recess width | 36 | 28–44 | 1 | Width of the shallow front label recess. |

All unlisted dimensions, topology and feature order remain fixed. Radius controls are radii, not diameters. These are independent numeric ranges; do not introduce unsupported formula bindings or assume a fit standard from an example value.
