Window Well Cover C-Clamp Retainer
This screw-down C-clamp replaces a cracked window well cover clip. It pinches the cover edge and the well's rim flange together with an M5 bolt and a nut held in a hex trap, so it grips any stack from about 0 to 17 mm thick without needing the original clip's profile. The clamp is 40 x 40 x 25 mm with an 18 mm jaw opening. A 5 x 12 mm slot in the top jaw takes an optional #10 screw into the cover, and the part prints on its side so layer lines don't take the clamping load.
