A nice physical habit tracker, that's designed like a monthly calendar. The design is a few separate parts so you can choose different colors, and the front grid is a very simple and fast print to replace each new month.
In order to ‘mark’ the days that you successfully did your habit, you snap off the square from the grid. This can be done easily with a toothpick or a pen (maybe also if you have nails). The connection is a single layer so it snaps off really easily.
The grid snaps on very easily, and the title part also. I created 12 different title pieces, each with a different month of the year. I'm also including the fusion360 file so you can edit it and change the texts if you want.
Notes for printing:
The author marked this model as their own original creation.
