For mine, I originally used 1/8" 48 pitch robinson racing car pinions from the local hobby shop. They worked ok on the 3mm shaft, but the smallest they make is 12 teeth. I ended up turning the end of the shaft down to 2mm, and using Orion micro RS4 pinions also from the lhs. I don't have a lathe, but just chucked the shaft in a drill press and used a file to grind down to 2mm.
