How to create variable spacing in this file

Hello,

Another member (Jonah Hawk) graciously made this definition in response to a previous post I made. I'm wondering if anyone can tell me how to create variable spacing between the triangular bays...right now they're evenly spaced. Or at the very least, how do I change the number of spaces (even if they stay the same)? Any tips would be very appreciated.

cheers,

marc
