moon calendar constructed

After designing and printing this i wanted to see how it would look if i printed each individual part separate and assembled in tiers. It is 34x34x8 on foam core and cardboard tubing.  The foam slightly warped so it isn't completely straight in places but i guess as a prototype its okay. On the constructed version i put in place 12 markers around the calendar itself just in case i decided to make a clock out of it and if i had any mechanical experience, making the moon circles gear operated would be awesome.  I think i will work on that and see if i can possibly make it.
