These upgrade parts for the "Woodpecker CNC 3018" and similar engraving machines (1610, 2418) are designed to add a LED strip recessed into the 2020 extrusion framework of the engraving machine.
Simply print and slide in, then glue your LED strip to them.
I used this LED strip in the project and connected it to the 12v+ port of the control board: https://www.ebay.co.uk/itm/Ultra-thin-5W-COB-60-LED-Car-DRL-Daytime-Running-Light-Lamp-Bar-Strip-20cm-1cm/392068893503
For this strip I used 3 mounts.
There is a small ridge on the reverse of the mount. This is so that you can fit the mount snugly into the framework extrusion. This will probably need to be filed down to ensure a snug fit in your own particular frame.
