could you please add keys for uhk?

[herrsimon]

Hello,

thanks a lot for making these files available! Could you please add the following non-standard sizes to support the ultimate hacking keyboard?

R1: 1.5U
Spacebars (or rather convex keys): 1U and 1.75U

The 1U convex key is needed for their thumb cluster.

Also, would it be possible to export the files in AI format and make them available here as well? I would like to contract somebody to make some wooden keycaps for me and he only accepts AI for his CNC machine.

Thanks in advance!
