[SMWS-08] Fix 3D model: Sensor hub holder – cable pass-through too narrow

**Description:**  
The cable hole in the sensor hub holder is correctly positioned, but the curved conduit (elbow) is too small. Thicker dipole wires cannot pass through.

**Tasks:**
- [ ] Widen or redesign the curved cable guide.
- [ ] Test fit with common dipole wire sizes.
- [ ] Export and upload updated STL.
