I made this ring because I didn't have any loose 1watt leds but I have plenty of the led light strips. So that is what I used.
Ring fits on bottom of platform with one extra hole to run wires through. My hot end still has 2mm to surface below the light ring, so I am not worried about impact. Also the light ring as designed only lights the surface of the part and I can look at it witout being blinded. Not too much light but enough too see well.
Led Light Strip 12v 300smd leds (16ft roll)
Cut off 3 sections (6") of the roll and then secured it on the inside of the ring with Loctite Go2 Glue (Higher temp tolerance)
