Micro-Grid Divisions (Microfinity Extension) + +**Official Gridfinity**: Only supports integer grid units (1U = 42mm). + +**Microfinity**: Adds support for fractional grid units: +- 0.25U (10.5mm pitch) - Quarter-grid +- 0.5U (21mm pitch) - Half-grid + +**Rationale**: Enables smaller storage for components like SMD parts, small hardware, and craft supplies. Maintains full compatibility with standard Gridfinity baseplates using micro-divided feet. + +### 2. Foot Profile Geometry + +**Official Gridfinity**: Uses specific chamfer dimensions derived from the original Fusion 360 model. + +**Microfinity**: Uses slightly different chamfer calculations to account for CAD precision: +- Bottom chamfer: 0.8mm (vs 0.99mm / sqrt(2) in some references) +- Top chamfer: Derived from total height minus other segments + +**Rationale**: Values are adjusted for CadQuery's precision requirements while maintaining fit compatibility. Actual printed parts fit correctly on standard baseplates. + +### 3. Stacking Lip Profile + +**Official Gridfinity**: Complex 5-segment profile with specific angles. + +**Microfinity**: Simplified but dimensionally equivalent profile that produces the same stacking behavior. + +**Rationale**: Easier to generate with CadQuery's extrusion system while maintaining correct stacking. + +### 4. Tolerance Values + +**Official Gridfinity**: 0.5mm total clearance (0.25mm per side). + +**Microfinity**: Same nominal values, but tolerances can be adjusted via spec file for different printer calibrations. + +**Rationale**: Different 3D printers have different dimensional accuracy. Spec-driven tolerances allow per-printer tuning. + +## Validation + +All spec values are validated at load time to ensure they fall within expected ranges: + +- Grid pitch must be exactly 42.0mm +- Height unit must be 6.0-8.0mm (nominal 7.0mm) +- Foot height must be 4.0-6.0mm (nominal 4.75mm) +- Wall thickness must be 0.5-2.0mm (nominal 1.0mm) + +See `microfinity/core/spec.py` for the full validation logic. + +## Contributing + +If you find discrepancies with the official Gridfinity specification or have measurements from Zack Freedman's original models, please open an issue with: + +1. The specific dimension in question +2. Your measured/reference value +3. Source of the reference (original CAD file, printed part measurements, etc.) -Any intentional deviations from the official Gridfinity spec are documented in the spec files with rationale. +We aim to maintain the closest possible compatibility with the official Gridfinity ecosystem.
