# Version 0.7 prototype printing guide

## Models

- `asterion_full_vehicle_1_to_50.stl` — visual portfolio model.
- `ring_drive_demonstrator_1_to_5.stl` — ring/spoke mechanism demonstrator.
- `docking_latch_demonstrator_1_to_5.stl` — simplified latch geometry.

## Suggested FDM settings

- Layer height: 0.20 mm for the vehicle, 0.16 mm for mechanisms.
- Walls: 3 perimeters.
- Infill: 15–25% for visual parts; 35% for mechanism handling.
- Material: PLA for display; PETG for repeated handling.
- Supports: generated only where required after slicer preview.
- Dimensional coupon: print a 20 mm cube and a hole gauge before mechanism parts.

These models are demonstrators, not flight hardware, pressure parts or load-rated components.
