Do you have problems seeing what is printing on your Ender 3? I designed these brackets in Tinkercad to mount to the top extrusion on the Ender 3 and hold the STBTECH LED Under Cabinet Light (https://smile.amazon.com/gp/product/B07R3SHDNN) Use the adhesive and metal disks from the light to hang the lightbar from these brackets. The front guard helps to keep the bright LEDs from blinding others in the room.
