These calendar cubes break apart in to two pieces, so that small objects can be stored or stashed inside them. The cubes are 50x50x50mm, so are small enough to stack in a variety of places. All 12 halves print together on one plate easily - minimising colour change waste.
The coloured text version has debossed the text by a small amount -0.01mm so that the deboss is not printed, however this means that it can be coloured easily using Bambu Slicer. The 3mf file included is pre-coloured.
There are 12 separate files (top and bottom for each of the 6 cubes) which have extruded the text inwards so it can be read. This is useful for printers without multi-material abilities. All 12 halves fit on one plate
The maths behind how you can track each day of the year using a few cubes as possible is somewhat intersting and is something I stumbled across when researching for the MakerWorld Calendar Competition. If you're mildy interested in that kind of thing too, it has a whole wikipedia page dedicated to it - The Two Cube Calendar Problem.
