## Design

- bases : preferably cubic, otherwise matching proportions of connected components (golden ratio, at least on one plane)
- core size + extension space (bolts, washers - max.), starting from 40x40, bounding box must be in even numbers
- up and down compatible by at least one size

## Implmentation

- SCAD tests (equation->render|step)
- OSR-AI tests & templates (NPL)

## Stock Sizes

- raw : 50x50 | 70x70 | 90x90 | 130x130
