Twin 18650 Hinged Pocket Carry Case
A clamshell case that prints in one piece with its hinge already assembled and carries two 18650 Li-ion cells (18.4 x 65 mm) in separate 19 mm half-round cradles, 66.5 mm long. It has a 4 mm captured-pin hinge with 0.5 mm clearances and a flexing snap tab, so loose cells in a pocket or bag can't short against keys or coins. Closed, it measures about 70 x 45 x 23 mm.
