# 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.

## 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.

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 wont tarnish the board.
