Heat sink dimensions?

I can’t find any sizing about the height, width and even depth of the heat sink. Maybe I’m crazy, but it’s not on any of the plans. I’m about to eyeball it, but I’d be more comfortable if anyone had the measurements?

if you print stefans plans out 1:1, you could measure it that way.

Roughly 2.25" x 2.25" x 5/8"
