Perpetual Desktop Month-Day Calendar

thingiverse

This calendar is straightforward - it consists of a holder and three rings for displaying the date. One ring features the months (1-12), another holds the day 'tens' (0-3), and the last displays the day 'ones' (0-9). The rings slot into the holder at the back, presenting the current date through a window. For distinction, I printed the month in orange and the day in purple. You can choose between US and European date formats. To change the date manually, simply reposition the rings. Printed on a Makerbot 2 using PLA filament with default settings, no supports were needed. The wheels may appear cleaner if printed at higher resolution to improve the visibility of numbers.
