The output of this tool may not be what you intended, or even a valid CAD file. Always verify correctness of the drawings before using them to produce parts.
If you use this tool to make plates, please let us know how it goes: email@example.com
Keyboard CAD Assistant takes layouts from keyboard-layout-editor.com and produces a CAD drawing that can be used to create a plate for mounting mechanical key switches.
Feedback welcome at firstname.lastname@example.org. Report bugs and request features at our issue tracker.
The border width is how far the plate will extend beyond the edge of the keycaps. A border of zero will result in the plate being flush with the caps.
Kerf is the width of material that the laser removes as it cuts (like the width of a saw blade). If you enter a kerf value, the drawing will be automatically adjusted to account for the width you provide. The value should be the total width removed on both sides of the center line.
Industrial laser cutters usually adjust for kerf automatically, and you shouldn't enter a value here. Check with your laser cutter operator to find out if you need to account for kerf.
Grid spacing is the distance between key switches measured center-to-center. Traditionally, switches are spaced 19.05mm apart, but 19mm works just as well. This setting needs to match the spacing on your PCB (if you are using a PCB) to ensure they are aligned.
There are overlapping holes in your drawing. This is probably unintended. 3d rendering will be unavailable.
