Based on SteffenBeck's model, I just added more cutouts in the main stand to lower the cost and print time of the model. Other 2 files are identical to the original files.
From Steffenbeck's model page : A box organizer for the game Hitster. The stand can also be used for holding the smartphone. The phone can then simply be put down and the cards inserted at the bottom. In my case it is an iPhone 13 (should also fit an iPhone 14). Modifying the stand for your smartphone should be very easy.
The author remixed this model.

Added more cutouts in the main insert, faster printing time and lowers the amount of filament used.
