Hộp đựng thẻ 3x5 Index Card Case

This is a card case, for which similar designs exist, that is intended to hold 3x5 flash cards. I made this when the bugs and drugs section of med school got a little out of hand and I decided regular flash cards would be better than Anki.  It's print in place, but you don't need to do it that way if you have a good filament with nice layer adhesion.
