This is a surface mount bracket for 1/2" (12.1-13.2mm) swivel arm type lamps like magnifier lamps used in workspaces. This will allow the user to mount the light to a horizontal surface like a shelf or desktop without needing the clamp typically used. As the long arm can exert significant torque at full extension, it is recommended to print the bracket with at least 4 walls and 25% infill or more. For my use case, I am utilizing 4mm machine screws secured by pronged t-nuts installed from the opposing side of the mounting surface to ensure the bracket stays firmly attached. I've included two sizes due to the variation of lamp posts that I myself have in my own shop in order to prevent slop at the pivot point.
