I just added a photo of simple and small PCBs which will act as a connector between the main PCB (main board sounds cooler) and the motor. As I stated earlier (or maybe I forgot) there are special (geared?) stepper motors for driving such things as tachometers, or other gauges in automotive industry. Just type "switec" in Google images and you'll get the idea. The problem is, that they are relatively expensive (few $) and relatively big. So my idea was to use those tiny motors you'll find on my photos, which I've got from China. I have no Idea what was their original purpose, but they suits me pretty well. This is a hack you might say, but well, we are on "hackaday" right?

To the point - I'll try to connect the motor and the PCB using another, tiny PCB (0.3mm == 12mils thick). Main board has a special slot (chink, crack? what is the proper word?). And the tiny ones, at one side have holes, like THT ones which will suit for the motor terminals, and the other side they will slide into the hole on the main board and the pads will be soldered together. I've seen such connections on few boards in the past, so hopefully I'll get nice working and nice looking results.
