Made this K'nex clock a long time ago and finally go to posting it. This will be all however if you wish to make it because I am not planning on making an I'ble. It uses a motor, and doesn't tell real time. The gear ratios make it something among the lines of 11 KSecs in a KMin and 11 KMin in a KHr (the "K"'s stand for K'nex). You should be able to use the photos if you want to make it easily.
