Perpetual Desktop Month-Day Calendar

pinshape

I frequently check what month and date it is during my workday. This calendar is straightforward - a holder with three rings: one for months (1-12), one for day tens, and one for day ones. The rings fit into the holder from the back, displaying today's date in a window. I printed the month in orange and the day in purple to make them stand out. You can choose between US month-day or European day-month order. To change the date, simply reposition the rings manually. I 3D-printed this calendar on my Makerbot 2 using standard PLA settings without supports. The wheels could benefit from higher resolution printing to make the numbers look sharper.
