I am building a 3D scanner out of an Xbox 360 Kinect motion camera and an old Yoga laptop. I needed a base to mount the Kinect so I designed this in OnShape and printed it out. It uses one 1/4-20 threaded insert from McMaster-Carr; part number 90975A025. Spring clips are printed separately so that they can be printed on their sides for best strength as a living hinge.
