The AS-5E3 Leynos is considered an evolution of the AS-3E Valken. While the Valken was a lighter cost-effective variant developed as part of the VTA project, the Leynos was a more comprehensive, heavily armed and armored platform.

The Leynos improved jumpjet system allowed it to quickly traverse relatively long distances and engage in limited aerial combat. In essence, the Leynos represented the next generation of jumpjet based frame design.

The All-In-One contains:

Pre-Supported .stl files
Unsupported .stl files
Pre-Supported Lychee file

The included .stl files have been extensively test printed, designed for 1/285 (6mm) scale wargaming and resin printers. All files are watertight, so can also be printed in filament. Easily up-scaled to 1/100 (15mm) by simply increasing the scale of the .stl files 230% in your chosen slicer.

All 6mm mecha stand roughly 35mm-50mm tall, depending if its a light, medium or heavy-class mech. Upscaling a medium-class 45mm tall mech to 15mm will give you a mecha standing roughly 100mm tall.
