Fluval Flex 57L light reflector
thingiverse
Update: I've made a new version that hangs down a tad more and has side covers. This prevents you from being blinded when standing to the side of the aquarium. A quick light reflector for the Fluval Flex 57L (15gal) aquarium lamp is now available. It simply slots into the gap between the lamp and lid. It also works well with the lid arms/props, as seen on https://www.thingiverse.com/thing:4007592. When lifting the lid and leaning it against the wall behind the aquarium, the lamp becomes useless for illuminating the aquarium and only blinds you. So I made this simple light reflector to shield me from the LEDs while directing some of that light downwards. The parts need to be glued together in the following steps: Align the "left" and "right" parts. Check which way the "middle" part fits on top. Add glue to the middle part and align it with the front edges of the left and right part. Once this is done, you can add some reflective or aluminum tape to the bottom of the reflector. I used aluminum foil instead, but tape would have been easier to apply.
