Arturia Keystep Janko Keys SCAD version

**This is still work in progress: I haven't printed and tested all the keys yet!**

I made an OpenSCAD version of TomsJensen's Arturia Keystep Janko mod so I could play around with the dimensions a bit.

You need [BOSL](https://github.com/revarbat/BOSL) if you want to modify the OpenSCAD file or re-export the STL files. There are a few things you can tune to tweak the gaps between the keys, the thickness of the key walls etc
