Hollow clock 2 remix

I made minor improvements: 1. Step motor mount with nylon screw and nut. Nut should be 5.6 mm (see picture attached) 2. Arduino and step motor drivers mount by 3mm screw and nut The main idea was to have all electronic components and wires open and visible, but properly fixed. Proper Arduino code could be found here https://www.instructables.com/Hollow-Clock-2/
