Microsoft Lifecam 3000 Servo Mount
This is a set of brackets designed to attach to standard servo horns (which may need to be drilled out), accommodating 8-32 bolts all around and giving pan/tilt functionality with 2 servos.
The Lifecam slides in and is held fairly securely by the tilt mount via friction. The flexible mount on the Lifecam can also be drilled through to accommodate an 8-32 bolt.
The base mount is designed to attach with 1/4" bolts.
