2026 perpetual calendar multifunctional modular calendar with plan progress slider vehicle restriction reminder remaining days photo frame pen holder stationery storage

Product Introduction:

1. Design Concept: Unlike many cool structures or mechanisms, I believe the most important aspect of a 3D printed calendar is its practicality. First, it must be useful and usable, and the text must be clear, otherwise, it loses its purpose as a calendar. Therefore, I focused on how to integrate dates, lunar solar terms, and compensatory leave into the calendar and display them clearly and conspicuously. Given that the layout of a 3D print is relatively small, it's challenging to clearly present so much content. After continuous attempts and layout adjustments, I planned the dates and lunar solar terms by distinguishing them with text and background colors. Red numbers indicate red-letter days for weekend holidays, white text on a red background signifies public holidays, black text on a gray background is for compensatory workdays, and black text on a white background is for normal working days. I have modeled and laid out all 12 months of the Gregorian and Lunar calendars, as well as holiday compensatory leave, and they can be printed directly. The text is large and very clear, making it easy to read.

2. Functional Design: This product incorporates many practical features. First, if you only want the calendar module, it can be printed separately and placed directly on the desk without needing to print other modules. Additionally, I have integrated functions such as photo placement, a plan progress tracking slider, a ruler, a pen and paper stationery storage box, handwritten paper notes, vehicle license plate restriction reminders, remaining days tracking, and more. All three major modules can be printed as needed, are installed with mortise and tenon joints or sliding rails, and their front, back, left, and right positions can be freely interchanged.

This product is mainly divided into three modules—A. Left calendar module. B.

The right side is dual-sided; the front is a plan progress bar slider, and the back can hold photos or papers for recording things, inserted into the photo frame. This module can be freely reversed and swapped. The top can also store stationery such as rulers, pens, and paper.

C. Base module: It combines vehicle license plate restriction functionality and remaining days tracking and reminder functions. The car icon slider can be moved to the restricted days, and the ring presses the remaining days button.
