Bike Helmet Light Mount - Dual and Single Light

This is a mount for the Bright Eyes bike light to mount to two different Giro Helmets. It uses one of the included rubber bands from the light kit to loop around a rib on the helmet. The smaller one is spaced for an 18mm rib and the larger one is spaced for a 33mm rib. There is a "fin" that screws to the light made out of PETG. The base can be printed from anything as there is no heat issue from the light. I have one printed in PETG and another in a firmer TPU. Both work well.
