# 5. Open-Top Electronics Enclosure With Bosses
|
|
|
|
|
|
|
|
## Prompt
|
|
|
|
Create a single solid open-top electronics enclosure base as a STEP model in millimeters.
|
|
|
|
The outer shape is a rectangular box 100 mm long in X, 70 mm wide in Y, and 30 mm tall in Z. Center it on the XY origin, with the bottom face at Z = 0.
|
|
|
|
The enclosure is open at the top. The wall thickness is 3 mm and the bottom floor thickness is 3 mm.
|
|
|
|
Add four internal cylindrical standoffs rising from the inside floor. Each standoff has an outside diameter of 10 mm and a height of 12 mm above the inside floor. Place the standoffs at X = +/-35 mm and Y = +/-25 mm.
|
|
|
|
Add a centered blind hole in each standoff, 3 mm in diameter and 8 mm deep from the top of the standoff.
|
|
|
|
Add 2 mm radius fillets to the four outside vertical corners of the enclosure.
|
|
|
|
Export as a STEP file.
|

| STEP import | File imports successfully |
|
|
| Solid count | One solid body representing the enclosure material |
|
|
| Outer dimensions | 100 x 70 x 30 mm |
|
|
| Placement | Centered on XY origin; bottom at Z = 0 |
|
|
| Top condition | Open top, not capped |
|
|
| Wall thickness | 3 mm |
|
|
| Floor thickness | 3 mm |
|
|
| Interior cavity | Correctly hollowed, with continuous walls and floor |
|
|
| Standoff count | Four |
|
|
| Standoff diameter | Diameter 10 mm |
|
|
| Standoff height | 12 mm above inside floor |
|
|
| Standoff locations | X = +/-35 mm, Y = +/-25 mm |
|
|
| Blind hole count | Four |
|
|
| Blind hole diameter | Diameter 3 mm |
|
|
| Blind hole depth | 8 mm from standoff top |
|
|
| Corner fillets | 2 mm radius on four outside vertical corners |
|
|
| Negative check | Blind holes must not break through floor; standoffs must not float |
