This is a two-color print. For mine, I used black for the background and white for the foreground. The hands are printed two-color as well with only the triangle printed in white. This makes the hands appear to be floating in air.

Note that I designed the clock face and the hands to fit this specific clock mechanism (comes as a 2-pack):

A different clock mechanism than the above might not fit perfectly. In this case, you may need to adjust the model somewhat. Then again, maybe the mechanisms are standard and you'll have no problem. I got a silent, non-ticking one because the ticking keeps me awake.

If you want just one, there's this one, but I haven't tried it:

Since I don't care about a second hand for this clock, I didn't create one. But some clock mechanism kits come with thin metal second hands that you could use.

The Case and Case Back are secured in place by four M4 x 35mm (or M4 x 36mm) bevel headed screws.

If you want to save plastic and screws, you can print the clock face without the case and print the small stand instead. It is just pressure-fitted into the back of the clock face.
