Parametric Cherry MX/Alps Keycap for Mechanical Keyboards by rsheldiii

KeyV2 is out!
This library is deprecated, and a new version has been released! please check it out here: KeyV2
Summary
I got halfway through making a parametric novelty keycap base before I realized there are decidedly few basic keycaps on the thingiverse website, so I took a detour to make a good one. This library has slowly grown to where you can generate keycaps in four different layouts in any length or height you desire! They are not quite drop-in replacements into existing keysets yet, but work great as a set, escape key, WASD cluster, top row, or as a base for an artisan.
Heavily modified from Kekstee's original Skull keycap to refactor, remove dxf files, add a dish, parameterize, and add a square keyswitch connector: https://github.com/kekstee/3dprint
Makerbot's customizer is great, but it's hard to zoom in and sluggish with spherical dishes, so you might be better served booting up OpenSCAD. Also, using OpenSCAD opens up a whole new level of customization! Due to the complexity of the key profiles things like dish depth, top skew, etc. can only be controlled from inside OpenSCAD. There are a lot of comments as to what things do so don't be afraid to dig around!
Features:
Many imitation key profiles supported! DCS, SA, DSA, and G20 for now. No OEM until I can find a good data sheet :(
Square Cherry key connector stem; easier to print. Circle and Alps available.
Stem inset now supported! allows you to print keys that will sit lower on the keyboard than before. you'll need to print with some kind of support.
Multiple dish types that affect the top and bottom, so keytop thickness is uniform throughout. Dishes are correctly created using a bit of trig, so they expand to arbitrary sized keycaps. Inverted dish types for spacebar / funky keyboards supported!
Keycaps can be arbitrarily wide or tall! note that for extra large keycaps you might need to turn up rounding on the dishes
Stabilizer supports! requires some digging for now, will add better support later
Experimental features:
Experimental ALPS compatibility!
Experimental rounded keycaps! Requires SCAD knowledge; replace key() with minkowski_key(). Will take FOREVER for anything with a dish due to polygons. G20 does not have a dish. results are pretty, but if you don't have a really good 3d printer you can safely skip.
Experimental ISO enter in the works. technically it is there, but it is the wrong size. you need to switch any use of shape_hull() for ISOEnterShapeHull(). I don't own any keyboards with it either so I have no idea if it actually fits or if it needs stabilizer holes (I assume so?) I just have keys I'm comparing it to from a grab bag.
Road to V2:
just need to do the customizer script now, with any luck we will be releasing soon
