Before you print

Mounting face 70 x 8 x 70; base 90 x 80 x 6. Motor fasteners use an example 31 x 31 mm pattern around Z=38. Confirm your motor drawing. Print on a side face; no torque or load rating. 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 **Foot**, a 90 × 80 × 6 box, centered at X=0, Y=0, with its bottom at Z=0.
2. Create **Motor face**, a 70 × 8 × 70 box, centered at X=0, Y=-30, with its bottom at Z=0.
3. Create **Left web**, a 6 × 52 × 40 box, centered at X=-32, Y=-8, with its bottom at Z=6.
4. Create **Right web**, a 6 × 52 × 40 box, centered at X=32, Y=-8, with its bottom at Z=6.
5. Unite **Foot**, **Motor face**, **Left web**, **Right web** as **Motor bracket blank**. Require one connected result.
6. Create **Motor opening**, radius 12, height 14, initially along +Z, with its base center at (0, -38, 38).
7. Rotate the current **Motor opening** solid -90 degrees around world X through [0, -38, 38]. Resolve the actual current entity ID before the operation.
8. Create **Motor bolt -15.5 22.5**, radius 1.7, height 14, initially along +Z, with its base center at (-15.5, -38, 22.5).
9. Rotate the current **Motor bolt -15.5 22.5** solid -90 degrees around world X through [-15.5, -38, 22.5]. Resolve the actual current entity ID before the operation.
10. Create **Motor bolt -15.5 53.5**, radius 1.7, height 14, initially along +Z, with its base center at (-15.5, -38, 53.5).
11. Rotate the current **Motor bolt -15.5 53.5** solid -90 degrees around world X through [-15.5, -38, 53.5]. Resolve the actual current entity ID before the operation.
12. Create **Motor bolt 15.5 22.5**, radius 1.7, height 14, initially along +Z, with its base center at (15.5, -38, 22.5).
13. Rotate the current **Motor bolt 15.5 22.5** solid -90 degrees around world X through [15.5, -38, 22.5]. Resolve the actual current entity ID before the operation.
14. Create **Motor bolt 15.5 53.5**, radius 1.7, height 14, initially along +Z, with its base center at (15.5, -38, 53.5).
15. Rotate the current **Motor bolt 15.5 53.5** solid -90 degrees around world X through [15.5, -38, 53.5]. Resolve the actual current entity ID before the operation.
16. Create **Left slot**, a 6 × 28 × 10 box, centered at X=-40, Y=20, with its bottom at Z=-1.
17. Create **Right slot**, a 6 × 28 × 10 box, centered at X=40, Y=20, with its bottom at Z=-1.
18. Subtract **Motor opening**, **Motor bolt -15.5 22.5**, **Motor bolt -15.5 53.5**, **Motor bolt 15.5 22.5**, **Motor bolt 15.5 53.5**, **Left slot**, **Right slot** from **Motor bracket blank**, consuming the tools; name the result **Motor mount**.

## Public controls

| Control | Default | Range | Step | Meaning |
| --- | ---: | --- | ---: | --- |
| Motor opening radius | 12 | 11.5–13 | 0.1 | Radius of the central motor clearance opening. |
| Left adjustment travel | 28 | 20–34 | 1 | Length of the left mounting slot. |
| Right adjustment travel | 28 | 20–34 | 1 | Length of the right mounting slot. |

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
Motor opening radius	12 mm	11.5–13 mm	0.1 mm
Left adjustment travel	28 mm	20–34 mm	1 mm
Right adjustment travel	28 mm	20–34 mm	1 mm
