Added some led’s to the frame of the delta today. They are warm white strips covered in packing tape to insulate from the aluminum extrusions. I slid them in the front two rails so that they are hidden. Not bad for $3 from aliexpress!
What is the size of the printer ?
@Americo_Foxnegro_Ren it is 1m tall with that build plate being 365mm in diameter.
I try to assemble one of 50 in diameter by 50 in height of print equal delta
I love it. I want to do the same with mine but there aren’t any good places on a prusa for those strips
me too even not find pieces in Mexico 
@Jordan_Cohen ever thought about adding some on the extruder? Printrbot has some new leds that do so.
@Griffin_Paquette ya! That is the “right” place to do it. Kind of like toolson…
Nice solution. Better than shining with a portable led light on your print.
@Marek_Lyczba thank you! I wanted to keep them hidden and the weight of the effector as low as possible.
