Ender 3 Light Bar

thingiverse

Simple light bar designed to securely attach an LED strip to a 20x20 extrusion at the top of your printer. A small test print is included to verify proper fitment within the extrusion. Each bar measures 150mm in length, so two bars should be printed to span the top of your printer. For optimal results, use silicone-coated LED strips that will stay in place without needing additional adhesive tape; however, uncoated LED strips may require double-sided tape for secure attachment. Print these bars vertically and you won't need any supports.
