| | 14 | /* |
| | 15 | * Feel free to use this .scad in your own projects to add proper Cherry MX-styled switch cutouts to keyboards, perhipherals, testers, or whatever you like. |
| | 16 | * You can just copy cherry_switch_void() into your own code if you like--it's entirely self-contained and reasonably small. Just make sure to credit, "This module was written by Riskable:" or something like that =) |

| | 20 | height: The thickness, really. Doesn't impact PLATE_THICKNESS |
| | 21 | x_extra: Extra (void) space on the X axis (e.g. to save some plastic). Doesn't change the top plate. |
| | 22 | y_extra: Extra (void) space on the Y axis. Same thing as X. |
| | 23 | tolerance: Extra room on all sides (0.1 default should be good for most printers) |
| | 24 | plate_thickness: How thick the top plate will be. Typical Cherry MX plates are about 1.5mm thick. |
