Initially, the model was created for manual translation of the hands using handles on the back of the dial. Now I have added a dial to create an electronic wall clock (clock face_1.stl) using a clock mechanism for a wall clock (example in the last photos) with hands and a hanger that can be bought online. The diameter of the dial is 180 mm, the thickness is 3 mm, the diameter of the inner hole is 8 mm.

When buying a watch mechanism, pay attention to the dimensions of the hands. The large hand is 80 mm, the small hand is 55 mm. If the hands differ greatly from the specified dimensions, then the size of the dial can be changed or carefully trim the hands.
