Dodecahedron Calendar

For the new year, print yourself a beautiful calendar~~~

On the first day of 2026, I made a dodecahedron calendar at home and wanted to share it with everyone.

It's printed in a single color; the days of the week and months are painted after printing. For multi-color printing, just choose your favorite colors.

The original design size was a bit large, so shrinking it to 70% for printing is just right. The attached 3mf file has already been scaled down to 70%, with the farthest two points about 21cm apart. When printed and placed on a desk, it still looks quite grand^_^

The months can be directly snapped onto the dodecahedron without adhesive. For a secure fit, the connection between the month cards and the dodecahedron is designed to be quite tight (0.1mm interference fit). If you find it difficult to assemble, you can sand down the edges of the protrusions on the month cards a bit.

I use a Bambu Lab P1S, and I recommend a printer speed of 50%. Since the month numbers are quite detailed, too fast a speed can cause distortion. When I printed at 100% speed with PLA Basic, the March card had an issue, so I reprinted it.

The calendar is for 2026 and has been set up by month; you can print it directly.

The dodecahedron base can be used indefinitely; just replace the month cards each year.
All parts are printed; no additional components are needed. Below are photos of the finished print.
