Before you print

Shell 140 x 100 x 56, 3 mm walls and floor; four PCB posts on 104 x 64 centers. Display window starts at Z=18 on the front wall. Two button holes are above it. No lid, electrical certification or weather 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 **Envelope**, a 140 × 100 × 56 box, centered at X=0, Y=0, with its bottom at Z=0.
2. Create **Interior**, a 134 × 94 × 60 box, centered at X=0, Y=0, with its bottom at Z=3.
3. Subtract **Interior** from **Envelope**, consuming the tools; name the result **Empty shell**.

6. Create **Post 52 -32**, radius 5, height 10, initially along +Z, with its base center at (52, -32, 3).
7. Create **Post 52 32**, radius 5, height 10, initially along +Z, with its base center at (52, 32, 3).
8. Create **Ear -79**, a 24 × 26 × 5 box, centered at X=-79, Y=0, with its bottom at Z=0.
9. Create **Ear 79**, a 24 × 26 × 5 box, centered at X=79, Y=0, with its bottom at Z=0.
10. Unite **Empty shell**, **Post -52 -32**, **Post -52 32**, **Post 52 -32**, **Post 52 32**, **Ear -79**, **Ear 79** as **Housing blank**. Require one connected result.
11. Create **Pilot -52 -32**, radius 1.6, height 15, initially along +Z, with its base center at (-52, -32, 3).
12. Create **Pilot -52 32**, radius 1.6, height 15, initially along +Z, with its base center at (-52, 32, 3).
13. Create **Pilot 52 -32**, radius 1.6, height 15, initially along +Z, with its base center at (52, -32, 3).
14. Create **Pilot 52 32**, radius 1.6, height 15, initially along +Z, with its base center at (52, 32, 3).
15. Create **Ear hole -81**, radius 3, height 8, initially along +Z, with its base center at (-81, 0, -1).
16. Create **Ear hole 81**, radius 3, height 8, initially along +Z, with its base center at (81, 0, -1).
17. Create **Display**, a 64 × 12 × 24 box, centered at X=0, Y=-50, with its bottom at Z=18.
18. Create **Button -18**, radius 3.5, height 12, initially along +Z, with its base center at (-18, -56, 49).
19. Rotate the current **Button -18** solid -90 degrees around world X through [-18, -56, 49]. Resolve the actual current entity ID before the operation.
20. Create **Button 18**, radius 3.5, height 12, initially along +Z, with its base center at (18, -56, 49).
21. Rotate the current **Button 18** solid -90 degrees around world X through [18, -56, 49]. Resolve the actual current entity ID before the operation.
22. Create **Power port**, radius 4, height 12, initially along +Z, with its base center at (64, 24, 24).
23. Rotate the current **Power port** solid 90 degrees around world Y through [64, 24, 24]. Resolve the actual current entity ID before the operation.
24. Create **Rear vent 0**, a 4 × 12 × 18 box, centered at X=-30, Y=50, with its bottom at Z=24.
25. Create **Rear vent 1**, a 4 × 12 × 18 box, centered at X=-18, Y=50, with its bottom at Z=24.

## Public controls

| Control | Default | Range | Step | Meaning |
| --- | ---: | --- | ---: | --- |
| Display opening width | 64 | 50–76 | 1 | Width of the front display aperture. |
| Display opening height | 24 | 18–26 | 1 | Height from the fixed Z=18 lower edge. |
| Power connector radius | 4 | 3–6 | 0.1 | Radius of the side power opening. |

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
Display opening width	64 mm	50–76 mm	1 mm
Display opening height	24 mm	18–26 mm	1 mm
