Card holder for many different style cards.
Was based off a version of a 2 x 4 that had saw blade width cuts in it to hold cards upright for children to easily see multiple cards at once.
Dimensions are 9"x3"x1-3/8"
Cuts are 1/8" thick.
I used 0.2 layer height, 3 walls and 15% infill. Takes just over 215 grams and roughly 3hrs and 43 min.
