Mechanical Calendar

I started this project because I was bored of the desk calendar I have that involves turning round blocks with numbers on every day. This mechanical calendar changes date automatically when you spin the large dial with the date on it, the day of the week changes and so does the month.

To assemble it you need to glue the centre cog to the stand and the other cogs push on.
On months that don't have 31 days you will have to take the 'days of week' dial off and change the day.

I only own a cheap 3D printer so the numbers aren't very clear, if anybody decides to print one please share under 'I made one' so I can see how it comes out with a better printer.
