Two different versions, one that fits un-sleeved cards a little more snugly, and one that fits sleeved cards. there's .100" difference in the width between both versions.
I've been able to print these off in PETG in Vase mode using a .8mm nozzle to save on material if you don't need something super sturdy, but want something more waterproof than a shoebox for your cards.
The author marked this model as their own original creation.
