# Universal Sign Generator
|
|
|
|
|
|
|
|
**Status:** Digitally validated for representative 3D constructions.
|
|
|
|
The editable generator is [universal-sign.scad](universal-sign.scad). FDM printing plus optional CNC, laser cutting, and engraving output.
|
|
|
|
## Defaults and important controls
|
|
|
|
Auto-sized rounded rectangular 3 mm plate with raised text and straight edges.
|
|
|
|
**Fit and tolerance:** Verify installed fonts and calibrate inlay, fold, kerf, and mounting dimensions.
|
|
|
|
Open the SCAD file in OpenSCAD and use **Window → Customizer** to change the documented parameters. Dimensions are millimetres.
|
|
|
|
## OpenSCAD and export
|
|
|
|
This generator requires a recent OpenSCAD Nightly build with `textmetrics` enabled.
|
|
|
|
1. Open the SCAD file and select parameters in Customizer.
|
|
2. Press **F6** for a full render.
|
|
3. Use **File → Export → Export as STL** for printable 3D output.
|
|
4. Slice with the actual printer, nozzle, material, and layer profile.
|
|
|
|

|
## Printing and fabrication
|
|
|
|
Print flat plates face-up or face-down as appropriate; inspect supports for desk assemblies.
|
|
|
|
The included STL files passed digital mesh and slicer checks. Digital validation does not establish physical fit, strength, fatigue life, or material suitability.
|
|
|
|
## Known limitations
|
|
|
|
- Accurate sizing requires OpenSCAD Nightly with textmetrics enabled.
|
|
- Desk joinery and inlays require physical calibration.
