I briefly considered using Klipper to make a clock that prints 1 layer per minute, but gave up after realizing it'd be unreadable after the first hour:
You could use multi material with color change on the hour. You don’t even need to flush the nozzle you could have the color gradually change throughout the layer, or print a handful of perimeters only between each hour.
You could have the first sector to be filled with a hole in the shape of the hour number. Then on the hour change print a couple of top layers covering the hole and print the next layer with the next number as a hole. It’s a really cool idea, as long as you don’t use a heated bed and manage your nozzle heating properly to keep your electric bill manageable. Also you definitely want low print speed and some TMC drivers hehe.
Well if your clock business doesn't take off you could always consider the wagon wheel or bicycle business!
