Round spacer

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 vertical cylinder named Outer, radius 10 mm and height 10 mm, with its bottom center at (0, 0, 0). Create a coaxial cylinder named Bore, radius 3 mm and height 40 mm, bottom center (0, 0, -5). Subtract Bore from Outer and consume the cutting tool. The result is one through-bored spacer. Keep both original cylinder features editable.

| Parameter | Default | Range | Step |
| --- | ---: | --- | ---: |
| Outer radius | 10 mm | 8–20 mm | 1 mm |
| Bore radius | 3 mm | 2–6 mm | 0.5 mm |
| Spacer height | 10 mm | 3–25 mm | 1 mm |
