If your passion for Tetris blossoms during the holiday season, then this Advent calendar is tailor-made for you!

Behind each of the 24 "doors" lies a small Tetris box, made with love and ready for your surprises. The magnetic Christmas tree frame creates an enchanting backdrop for your unique arrangement of Tetris boxes.

Both the boxes and the frame magnetically adhere to each other for optimal support of the boxes within the frame. The magnets are optional but highly recommended to prevent the accidental displacement of other boxes when pulling them from the "doors." You can start with 48 magnets if placed correctly, or go all-in with the full 178 to fill every box and the frame completely. But don't forget about the polarity!

The lids close with a satisfying click and are sturdy enough to secure everything.
Simple assembly – no glue, screws, or elaborate processing, and all of this, even without support, has been implemented throughout the entire calendar.

If you need more tolerance for the magnets, you have the choice between two box versions – normal and loose fit, providing an extra 0.4mm of space, which should be more than enough. For the lids, you can choose between two designs – without a hole or with a small hole into which the numbers 1 to 24 can comfortably and securely fit. Everything is easy to assemble, and the magnets can also be easily inserted with some pressure – (in case of emergency, a gentle tap with a hammer can help!)
The entire calendar has a default size of 4x4x4 cm, but you can scale it to 3x3x3 for faster printing or 5x5x5 cm for more space as desired (but you have to cut the frame in more pieces). (Other sizes have not been tested.) Here are a few examples of how you can fill the frame:
