Custom modeled holder for front light LED's for Arrma Vorteks RC car. I used 4 cheap led's cluster with appropriate connector allowing to connect them to rc receiver on car. Printed from FLEX, whic allows to put led's inside tunnels, ends of leds are thus covered by material as well. Holder is slightly thicker, then the space inside the bumper, but as it is from ‘rubber’ it could be pressed by fastening screws, which fastens the holder inside. It needs bit of support for the side holes on tubes, which needs to be removed later. Works good for me.
