Where are my custom Dota 2 item builds saved?

I did a custom build for Pudge and I want to backup it so i can try out this custom build manager :D2RIC_1.3.3

I only found the default ones in C:\Program Files (x86)\Steam\SteamApps\common\dota 2 beta\dota\itembuilds and its subfolder.

So does anyone know the exact path?

\Steam\userdata\XXX\570\remote\itembuilds
