A case designed from the ground up for carrying a deck of playing cards in my EDC backpack. The tolerances are very tight, with a standard deck of Bicycle cards hardly making a rattle in it. The sliding lid might require a smidge of sanding to fit perfectly. Although not tested, the lid should be splash and dust resistant to an extent with such a tight fit. A registration bump was added that can be oriented up or down.

The only support needed is in the lid hole. There are small built in supports around the top to support the sliding channel. They are easily popped or clipped off. Printed in PLA with no raft or brim.
