Before you print

Flange 90 x 90 x 6; tapered outside from diameter 60 at Z=6 to 40 at Z=40. Default cuff diameter 40, ending Z=62. Retention beads diameter 44. Adjust cuff outer radius, cuff height and one fastener seat. The bore stays fixed. Not pressure rated. Geometry has been digitally checked; this template has not been physically test-printed.

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 **Flange**, a 90 × 90 × 6 box, centered at X=0, Y=0, with its bottom at Z=0.
2. Create **Transition**, a frustum with bottom radius 30, top radius 20 and height 34, base center (0, 0, 6).
3. Create **Cuff**, radius 20, height 22, initially along +Z, with its base center at (0, 0, 40).
4. Create **Retention bead lower**, radius 22, height 3, initially along +Z, with its base center at (0, 0, 45).
5. Create **Retention bead upper**, radius 22, height 3, initially along +Z, with its base center at (0, 0, 55).
6. Unite **Flange**, **Transition**, **Cuff**, **Retention bead lower**, **Retention bead upper** as **Reducer blank**. Require one connected result.
7. Create **Lower bore**, radius 27, height 8, initially along +Z, with its base center at (0, 0, -1).
8. Create **Tapered passage**, a frustum with bottom radius 27, top radius 17 and height 34, base center (0, 0, 6).
9. Create **Upper bore**, radius 17, height 30, initially along +Z, with its base center at (0, 0, 39).
10. Create **Bolt -35 -35**, radius 2.75, height 10, initially along +Z, with its base center at (-35, -35, -1).
11. Create **Seat -35 -35**, radius 5, height 3, initially along +Z, with its base center at (-35, -35, 3).
12. Create **Bolt -35 35**, radius 2.75, height 10, initially along +Z, with its base center at (-35, 35, -1).
13. Create **Seat -35 35**, radius 5, height 3, initially along +Z, with its base center at (-35, 35, 3).
14. Create **Bolt 35 -35**, radius 2.75, height 10, initially along +Z, with its base center at (35, -35, -1).
15. Create **Seat 35 -35**, radius 5, height 3, initially along +Z, with its base center at (35, -35, 3).
16. Create **Bolt 35 35**, radius 2.75, height 10, initially along +Z, with its base center at (35, 35, -1).
17. Create **Seat 35 35**, radius 5, height 3, initially along +Z, with its base center at (35, 35, 3).
18. Subtract **Lower bore**, **Tapered passage**, **Upper bore**, **Bolt -35 -35**, **Seat -35 -35**, **Bolt -35 35**, **Seat -35 35**, **Bolt 35 -35**, **Seat 35 -35**, **Bolt 35 35**, **Seat 35 35** from **Reducer blank**, consuming the tools; name the result **Hose reducer**.

## Public controls

| Control | Default | Range | Step | Meaning |
| --- | ---: | --- | ---: | --- |
| Hose cuff outer radius | 20 | 19–21 | 0.1 | Outer radius between the two fixed retention beads; match the hose inside diameter. |
| Hose cuff height | 22 | 20–28 | 1 | Length above the tapered section. |
| Fastener seat A radius | 5 | 4.5–6 | 0.1 | Recess radius for the first mounting screw head. |

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.

Adjustable dimensions

Parameter	Default	Range	Step
Hose cuff outer radius	20 mm	19–21 mm	0.1 mm
Hose cuff height	22 mm	20–28 mm	1 mm
Fastener seat A radius	5 mm	4.5–6 mm	0.1 mm
