Before you print

Flange diameter 36, barrel diameter 28; flange-to-flange length 24; total hub length 30. Three upper and three lower relief pockets are blind and leave a central web. For low-load prototypes; check axle retention and actual service conditions. 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 **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.

Adjustable dimensions

Parameter	Default	Range	Step
Axle bore radius	3.2 mm	2.5–4 mm	0.1 mm
Upper washer radius	5.5 mm	5–6 mm	0.1 mm
Lower washer radius	5.5 mm	5–6 mm	0.1 mm
