I got the inspiration for this project from a contribution on Thingiverse. I completely redesigned the case, added a stand, prepared it for battery operation, changed the number cubes and occupied all the cube faces. Primarily, I wanted to print the clock for my grandchildren to learn how to tell time. For this, there are play hands that can be inserted into the clock case. However, I thought it would be a "shame" to use the clock only as a learning toy. Therefore, I designed the clock in a way that it can also be used as a normal clock with a battery-powered movement. Then, of course, it depends on the color design to what extent this clock can also please an adult. For children, the colours should be appropriate for children. The clock face can be customized with the number cubes for practicing clock times. There are a total of 6 different ways to insert the cubes into the case, with the letters (AS TIME GOES BY) and the point surfaces being more in the fun area. Once children have mastered reading the times, the play/exercise hands can be replaced with a battery operated movement. The clock can be wall mounted or placed on a stand.
