24h Wall Clock
Why?
Couldn't find a wall clock design I liked so made my own.
No, but why?
I like the idea of a timepiece with one revolution per day instead of the one we're used to. Clock face was designed in OpenSCAD as manually positioning hour segments and applying changes would be very cumbersome. 12 on top due to personal preference: daytime on top, nighttime on bottom (as indicated by the sun and moon).
Engraving & Cutting with Laser
As RDworks fails to properly read in the DXF exported by OpenSCAD, a detour through Inkscape is necessary (unless using Lightburn, I presume). If not using RDworks, skip following. From OpenSCAD export as SVG. In Inkscape save the exported SVG as a DXF file. That DXF file can be opened in RDworks. Same procedure has to be done with part_clock_outline.scad to use as a cutting outline.
Tips:
- Cut against the wood grain, not along (as in + not =).
- Mask the board with tape (painters or masking tape, the paper kind). This way smoke and soot won't tarnish the board.
On a 100W CO2 Laser With following properties:
- Engraving layer: 350mm/s@30% power
- Number edge cutting layer: 50mm/s@10%
- Outline cutting layer: 25mm/s@45%
Timing
- Engraving took ~45 min
- Number edge cutting ~3 min
- Outline cutting <1 min
