New clockface for Hollow clock with flying hands

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4808950.

I made a new clock face which covers the teeth of the minutes hand. It looks better and now it is not so easy to guess how the clock works. For printers with a not so big build volume (like mine) I made a splitted version too. It is also compatible with the modified base for the ESP8266.
