Before you print

Base 110 x 80 x 8. Bearing axes run along Y at X=0,Z=38. Supports are 16 mm thick, centered at Y=-24 and +24. Outside bearing-ring diameter 40. Bore sizes adapt measured bearings; add separate retainers. 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 **Base**, a 110 × 80 × 8 box, centered at X=0, Y=0, with its bottom at Z=0.
2. Create **Pedestal -24**, a 32 × 16 × 30 box, centered at X=0, Y=-24, with its bottom at Z=8.
3. Create **Ring -24**, radius 20, height 16, initially along +Z, with its base center at (0, -32, 38).
4. Rotate the current **Ring -24** solid -90 degrees around world X through [0, -32, 38]. Resolve the actual current entity ID before the operation.
5. Create **Pedestal 24**, a 32 × 16 × 30 box, centered at X=0, Y=24, with its bottom at Z=8.
6. Create **Ring 24**, radius 20, height 16, initially along +Z, with its base center at (0, 16, 38).
7. Rotate the current **Ring 24** solid -90 degrees around world X through [0, 16, 38]. Resolve the actual current entity ID before the operation.
8. Create **Side stiffener -28**, a 8 × 68 × 10 box, centered at X=-28, Y=0, with its bottom at Z=8.
9. Create **Side stiffener 28**, a 8 × 68 × 10 box, centered at X=28, Y=0, with its bottom at Z=8.
10. Unite **Base**, **Pedestal -24**, **Ring -24**, **Pedestal 24**, **Ring 24**, **Side stiffener -28**, **Side stiffener 28** as **Pedestal blank**. Require one connected result.
11. Create **Bearing -24**, radius 11.1, height 20, initially along +Z, with its base center at (0, -34, 38).
12. Rotate the current **Bearing -24** solid -90 degrees around world X through [0, -34, 38]. Resolve the actual current entity ID before the operation.
13. Create **Bearing 24**, radius 11.1, height 20, initially along +Z, with its base center at (0, 14, 38).
14. Rotate the current **Bearing 24** solid -90 degrees around world X through [0, 14, 38]. Resolve the actual current entity ID before the operation.
15. Create **Mount -44 -28**, radius 3.25, height 12, initially along +Z, with its base center at (-44, -28, -1).
16. Create **Mount -44 28**, radius 3.25, height 12, initially along +Z, with its base center at (-44, 28, -1).
17. Create **Mount 44 -28**, radius 3.25, height 12, initially along +Z, with its base center at (44, -28, -1).
18. Create **Mount 44 28**, radius 3.25, height 12, initially along +Z, with its base center at (44, 28, -1).
19. Create **Service window**, a 28 × 22 × 12 box, centered at X=0, Y=0, with its bottom at Z=-1.
20. Subtract **Bearing -24**, **Bearing 24**, **Mount -44 -28**, **Mount -44 28**, **Mount 44 -28**, **Mount 44 28**, **Service window** from **Pedestal blank**, consuming the tools; name the result **Twin bearing pedestal**.

## Public controls

| Control | Default | Range | Step | Meaning |
| --- | ---: | --- | ---: | --- |
| Front bearing radius | 11.1 | 10–12 | 0.1 | Front bearing seat radius, including measured fit allowance. |
| Rear bearing radius | 11.1 | 10–12 | 0.1 | Rear bearing seat radius, including measured fit allowance. |
| Service window width | 28 | 22–36 | 1 | Width of the central through-window in the base. |

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
Front bearing radius	11.1 mm	10–12 mm	0.1 mm
Rear bearing radius	11.1 mm	10–12 mm	0.1 mm
Service window width	28 mm	22–36 mm	1 mm
