AI CAD prompt: Flanged replacement guide roller

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 **Lower flange**, radius 18, height 3, initially along +Z, with its base center at (0, 0, 0).
2. Create **Barrel**, radius 14, height 18, initially along +Z, with its base center at (0, 0, 3).
3. Create **Upper flange**, radius 18, height 3, initially along +Z, with its base center at (0, 0, 21).
4. Create **Axle hub**, radius 7, height 30, initially along +Z, with its base center at (0, 0, 0).
5. Unite **Lower flange**, **Barrel**, **Upper flange**, **Axle hub** as **Roller blank**. Require one connected result.
6. Create **Axle bore**, radius 3.2, height 34, initially along +Z, with its base center at (0, 0, -1).
7. Create **Upper washer**, radius 5.5, height 5, initially along +Z, with its base center at (0, 0, 27).
8. Create **Lower washer**, radius 5.5, height 2, initially along +Z, with its base center at (0, 0, 0).
9. Create **Lower relief 0**, radius 2.6, height 8, initially along +Z, with its base center at (10, 0, 0).
10. Create **Upper relief 0**, radius 2.6, height 8, initially along +Z, with its base center at (10, 0, 16).
11. Create **Lower relief 1**, radius 2.6, height 8, initially along +Z, with its base center at (-4.999999999999998, 8.660254037844387, 0).
12. Create **Upper relief 1**, radius 2.6, height 8, initially along +Z, with its base center at (-4.999999999999998, 8.660254037844387, 16).
13. Create **Lower relief 2**, radius 2.6, height 8, initially along +Z, with its base center at (-5.000000000000004, -8.660254037844386, 0).
14. Create **Upper relief 2**, radius 2.6, height 8, initially along +Z, with its base center at (-5.000000000000004, -8.660254037844386, 16).
15. Subtract **Axle bore**, **Upper washer**, **Lower washer**, **Lower relief 0**, **Upper relief 0**, **Lower relief 1**, **Upper relief 1**, **Lower relief 2**, **Upper relief 2** from **Roller blank**, consuming the tools; name the result **Guide roller**.

## Public controls

| Control | Default | Range | Step | Meaning |
| --- | ---: | --- | ---: | --- |
| Axle bore radius | 3.2 | 2.5–4 | 0.1 | Axle clearance radius through the central web. |
| Upper washer radius | 5.5 | 5–6 | 0.1 | Radius of the upper washer pocket. |
| Lower washer radius | 5.5 | 5–6 | 0.1 | Radius of the lower washer pocket. |

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.
