Summary A simple mount for a USB extension cable to mount a key chain LED light (or other things) to your printer's frame. I used a T-nut and bolt that came as spare parts with the CR-10 to mount it to the frame. To use it on the other side, just flip the design in your slicer. P.S. where it says M3 in the pictures i believe it's an M4 bolt. Either way, it's one of the spares that came with your printer ;) P.P.S. If this firts other printers, please share, so I can let people know here as well. Thanks!
