About this 3D model
After I redesigned the wheel, I went back to the face and made some changes. I added a background for appearance then a minute arc, 0-60, a 30 degree swing. Then after looking at that for a while it made me think some more. I added another arc to show minutes before the next hour. The minutes are still displayed on dial at bottom. I got the idea of just using just a face instead of a box from a remake of my earlier design. http://www.thingiverse.com/thing:327530. Thanks. Different makers make different ideas. Just making, that's all.
