Summary

A simple clock. There are two versions: one used a CD for the face, the other a disc recovered from a hard drive. Print the base, hub, and outer disc for the the one you are using. The holder for the clock mechanism is the same for both. The mechanism itself is a Quartex one, though other makes might fit as well. I printed this with nGen, which tends to swell a little, and for other materials you might need to adjust the exact sizes. The blender files are included.
