SD Card Single Case Holder

SD memory card case, minimal size design for one card or adapter card.

Works really well, sliding top is not too tight or too loose.
I designed this many weeks ago, I often carry one in a pocket and it doesn't open when you don't want it to.
The lid is symmetrical, it doesn't matter which end you put in first.

Dimensions: 5mm x 30mm x 40mm

UPDATE: I have added a chamfer to the bottom and relief for a lanyard.
