Peripheral device with limited relative angular movement

A peripheral device configured for detachable operative interconnection with a computing device, the peripheral device comprising:

• a. a first portion including a first hinge portion, which defines an axis of rotation, and comprises a first protrusion and a second protrusion, the first protrusion disposed axially separated at a predetermined distance from the second protrusion;
• b. a second portion including a second hinge portion which is operatively interconnected with the first hinge portion to allow the first portion and the second portion to rotate relative to one another about the axis of rotation between a first angle and a second angle;
• said first angle and said second angle at least in art defined b said first protrusion and said second protrusion;
• and c. an operatively connected peripheral device component;
• wherein the first hinge portion defines one or more indentations at an outer surface of the first hinge portion, the peripheral device further comprising a rotational retention mechanism including one or more resiliently biased balls configured to engage one or more of the indentations.
