A small organizer that can hold up to 100 A6 Flash Cards. You can simply grab a card, write your todos, and insert it into the small gap for display. Perfect for your workplace, nightstand, or wherever you need todos :D

I printed it in White Pearl Prusamen PLA. Layer height 0.25mm and 5% infill without supports.

This site also contains a version with a small notch to hold a pen in reach.
