The Kinetic Dynamo has a yellow dot on top that suggests the location where electrical connectors can placed there. Nonetheless, the connectors will still work even if placed on other faces of the Dynamo, but this isn't obvious or intuitive. I suggest to have the yellow on the other faces of the Dynamo too.

It'd be good enough if the dot was only on the grey faces, I feel. The coil face would be easily implied.

Wouldn't really look good on the sides, given there's the coil texture there. Plus, nothing in the manual say you can only draw from the top =P
