Perpetual Desktop Calendar

Redesigned rings of the original calendar using OpenScad (source included):

1. rings could be printed without supports
2. rings are much more lightweight, less plastic and faster to print
3. text on rings could be printed in different color (instructions below)
4. rings are fully parametrizable, you can change text on rings if you want.

The base and front window were taken from the original design.

To print text in separate color, slice ring and corresponding text separately, making sure they align properly. Then print text first, replace plastic and print the rest of the ring.
