# Universal Clock Dial
|
|
|
|
|
|
|
|
**Status:** Digitally validated; movement fit and hand clearance require physical checks.
|
|
|
|
The editable generator is [universal-clock-dial.scad](universal-clock-dial.scad). FDM printing plus optional laser, CNC, vinyl, or plotter workflows.
|
|
|
|
## Defaults and important controls
|
|
|
|
180 mm round, 3 mm thick dial with 8.2 mm centre hole, rings, track, numbers, and text.
|
|
|
|
**Fit and tolerance:** Measure the clock movement shaft, recess, and hand stack before manufacturing.
|
|
|
|
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 the dial flat on its rear face.
|
|
|
|
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
|
|
|
|
- Requires OpenSCAD Nightly with textmetrics enabled.
|
|
- Fine marks and text must match the nozzle or tool resolution.
