About this 3D model

2024-1-4 updates: upload step file for people who want to remix it to be their language. This is a calendar driven by gears. Rotate the "week roller", and the large "date ring" will follow the "week roller". You need to adjust the gear at the end of each short month, as shown below. Press the "date ring" and rotate the "week roller" to the correct position. I put 3 options in one 3MF file。 The first plate is single color, if you wanna quick print, just use this plate only. Printing time about 2 hours. The second plate is dual color, Printing time about 7 hours. The third plate is dual color but optimized design, but it need your additional time for install skin to the rollers. Printing time is about 4 hours. Don`t use this one, if you feel your handwork not good. Below explosion view to show you how to assemble components together. Please refer to below picture for assemble skin to roller.
