I love this cute little motor! The plus sign connector fits almost perfectly on a Lego Technics gear. You have to use some epoxy to fill in the gap but I found it to be the best way to connect it to my project. The internal gearing gets it pretty slow already but I needed it slower and didn't have much room in my project for more gears so i have it connected to a single AA battery for 1.5v. it's a little underpowered with that but it works fine.

Great little motor
It is a great little motor for slow moving parts. Problem is that there is nothing around that I could find that would mate to the "+" shaped interface. No gears, or wheels. will have to make your own parts.
