About this 3D model

This is a calendar puzzle designed by me. It is a sliding puzzle calendar. The sliding blocks can be used to adjust the date of each month and ensure that the 1st of each month is on the correct day of the week. I hope you enjoy it and I hope everyone can be inspired to model their own calendar. Please indicate the source of inspiration. This model is free and should not be pirated or used for commercial purposes. In short, I hope it helps you.
