3D render of the Cube Desk Calendar: two white cubes showing 14 and a teal bar showing OCT in a graphite stand
Free 3D model

Cube Desk Calendar

A desk calendar you never have to replace. Turn the two cubes to show the date and the bar in front to show the month. Two cubes are enough for every date from 01 to 31: one has 0 to 5, the other 0, 1, 2, 6, 7 and 8, and the 6 turned upside down is the 9. Each of the three bars carries four months. The stand holds the cubes and the bar you need, with the two spare bars out of sight behind the cubes. The numbers and letters are debossed, ready to fill with paint.

Also needed

Parts you buy

  • Nothing else to make it work.
  • To make the numbers stand out: acrylic paint or a paint marker in a contrasting colour. Brush it into the debossed numbers and letters and wipe the face clean with a damp cloth before it dries.
  • Optional: four self-adhesive rubber bumpers, 10 mm across, for the recesses under the stand.

Assembly

How to build it

Print the parts

Print the cubes on any face and the bars lying on a long side. Turn on elephant's foot compensation (about 0.15 mm) so the bottom edges don't flare out; the cubes and bars have 0.4 mm play in the stand.

Fill the numbers

Optional: brush acrylic paint into the numbers and letters and wipe the faces clean while it is still wet. A paint marker works too.

Set up the stand

Stick the rubber bumpers into the recesses under the stand if you use them. Put the bar with the current month in the channel at the front and the other two in the tray at the back.

Set the date

Put the cubes in their pockets with the date facing you. For 01 to 09, the 0 can go on either cube. For a 9, turn the 6 upside down, so its bar sits above it.

Every month

Turn the bar a quarter turn to the next month. After April and August, swap it for the next bar from the back.
