Flashcard Box - Leitner system

A simple box for flashcards. The compartments are of different lengths so that they are proportional to the number of flashcards.I use the box in the following way (Leitner system):Section 1 - I repeat every daySection 2 - I repeat every two daysSection 3 - I repeat every weekSection 4 - I repeat every two weeksSection 5 - I repeat once a monthSection 6 - blank cards / I already know This is my first version and the walls are thick. This makes the box very durable, but you can easily make thinner walls to save filament. Write in the comments if you want this version and I will make it.Dimensions: 100x188x35 mmRecommended card dimensions: 88mm x 49mm (~ 1/2mm)You can get these cards on Aliexpress under the phrase: 100pcs paper card. Link If you like the project, I would appreciate it if you could leave a like and boost. Then I will try to make another, better version.
