Simple Index Card Holder
thingiverse
I wasn't very impressed with a lot of the notecard/index card holders here on Thingiverse, so I made my own! ***Ideal for 3" x 5" Notecards!*** There's enough space for the notecards to be straight, it only appears like there isn't because the notecards have a natural bend to them. You should be able to comfortably fit about 80 cards in here, although I expect 100 is possible if you're fine with a tight fit. Feel free to print with exclusive slicing in Cura to get thinner walls. If I ever revisit this (which is unlikely), I'll try to add a thinner version.
