# 3D explorer

Turn the whole ship around, pull it apart, cut it in half and look at the electronics under the plate. It works on an iPad.

## How to use it

| Control | What it does |
|---|---|
| Drag | Turn the ship |
| Pinch or scroll | Zoom in and out |
| Double-tap | Reset the view |
| **Explode** slider | Pull all parts apart |
| **Cut in half** | Slice the ship through the middle to see inside |
| **Lights on** | Night mode: the LEDs glow in the diffuser |
| **Under** | Look from below, at the electronics |
| Part names | Tap to hide or show a part and read what it is |
| **Model A / Model B** | Switch between the two designs. See [Model A or Model B?](models.md) |

## What to look for

- **Model A:** the electronics are only under the base plate: the copper rails, the battery holder with its switch and the three LEDs.
- **Model B:** the holder is under the plate, two wires come up through the plate to the copper rails on the power panel, and the LEDs face outward.
- Panels and wings are different parts. Their slots are different lengths, so they cannot be mixed up.
- Hide the panels and the nose cone to see how the plate, the rails and the diffuser fit together.

## Download the meshes

The same model is available as STL files in the repository: [`3d/preview`](https://github.com/HisarCS/fablibrary/tree/main/projects/welcome-space/3d/preview). Open them in any 3D viewer or slicer preview.

!!! warning "Preview, not for printing"
    The model is built from the numbers in the drawings and simplified: the nose-cone slots and the diffuser switch window are not shown. Print from the OpenSCAD files. Real shape and fit are confirmed only after the first prototype is built.
