Reelight RL720 front headlamp.

thingiverse

I had an accident with my Reelight RL720 and lost the front lens in traffic. Reelight refused to provide a replacement part, so I came up with this model instead. The PETG clear print is good enough for visibility but not as clear or bright as the original lens. Maybe someone else will have better luck making PETG transparent or casting in resin. The friction fit on this model works well enough for me, but you may want to add some adhesive to be sure it stays secure.
