Countdown Display for everything

A display that shows how many days you have to wait.

What you need to print for 2 numerals:
1x right.stl
1x left.stl
4x role.stl
2x crank.stl
2x Numbers and signs(with example).pdf (in your normal paper printer)
2x cover.stl

or

1x everything you need.stl

Assembly instructions:
When you printed out everything glue the crank.stl parts together and cut out the paper along the line, glue the paper together (with transparent tape) in a row and write on the sign. Put the roll parts together (no need to glue them) so that you get 4 rolls. Hang the rolls between the paper and lower them into the box. Now insert the crank through the box into the roll from one side and the axle from the other side. Then you're done with the assembly! Now you always know how many days are left until a special day.
