First, you'll need OpenSCAD: http://www.openscad.org/downloads.html. I highly recommend installing the development snapshot, as they generally support more features and are relatively stable. Development snapshots are listed in their own section on the downloads page.
After you have openSCAD installed, you need to download the code and run it. running `git clone https://github.com/rsheldiii/openSCAD-projects.git` if you have git, or downloading [this zip](https://github.com/rsheldiii/openSCAD-projects/archive/master.zip) and extracting the directory should do it.
To make your own key, all you need to do is open `keys.scad` with openSCAD and modify this line:
```
dcs_row(5) legend("⇪", size=9) key();
```
To be whatever you want. For example, this is for a ctrl key on an OEM keyboard:
```u(1.25) oem_row(3) legend("ctrl", size=4.5) key();```
It is possible to edit this project with an external editor by checking off Design => 'Automatic Reload and Preview' in OpenSCAD.

## TODO:
moved to [TODO doc](./TODO.md)
* replace linear_extrude_shape_hull with skin_extrude_shape_hull or something, to enable concave extrusions
* replace current ISO enter shape with one that works for `skin()`
* generate dishes via math?

TODO:
* implement key_shape_at_progress which allows you to query for the exact 2d outline of the keycap at a given height
* this makes certain functions easier - building the envelope for instance
* requires breaking out shape_slice, and creating a polygon of the skin_shape_slice slices
* dishes add / remove height from keycaps, particularly spherical dishes
* a bandaid solution would be to allow you to modify where the keytop is along the progression of the keycap
* you can't just set a new total_depth because of how width_difference and height_difference work
* the true solution would be to rewrite how the dishes work to make them very graduated at the edges
* Make flat stem support default
* make flat inner shape default
* support repositioning to print on the back surface of the keycap
* implement regular polygon for skin extrusions
* switch to skin-shaped extrusions by default
* kailh choc has a non-square key unit; should I get that working for layouts etc?
