KeyV2/keys.scad

// the point of this file is to be a sort of DSL for constructing keycaps.
// when you create a method chain you are just changing the parameters
// key.scad uses, it doesn't generate anything itself until the end. This
// makes it remain easy to use key.scad like before (except without key profiles)
// without having to rely on this file. Unfortunately that means setting tons of
// special variables, but that's a limitation of SCAD we'll have to work around

/* TODO:
 * fix stem inset
 * can now measure keycaps very accurately. need to redo measurements: [x] SA [ ] DCS [ ] DSA [ ] OEM?
 * make OEM profile from my WASD keyset
 * Pregenerated keysets for DCS (rounded tops too intense) WITH rounded spacebar [ ] 60% [ ] TKL [ ] full
 * Add inset stem to all profiles that need it (DCS?)
 * sideways cylindrical dish needs to be used for some spacebars but not others. currently none of them use it
 * generate dishes via math? kind of hard
 * customizer version where everything is copy/pasted in
