This is a Logitech c170 camera mount for the MP Select Mini. Each Link goes attached to the next one with M3 bolts and nuts. Any link can be attached to the camera using the little plastic rod that came with the camera hinge (or a 35mm M3 bolt). The only difference in the Link_to_camera STL file is a non centered attaching arms (little displacement to the right) to center the camera view in relation to the bed (but is optional).
