I'm setting up a couple tanks with these little inexpensive lights, and I came across a couple very helpful 3D printable add-ons I wanted to pass along.
Note that while using PLA polylactic acid filament is perfectly adequate for the shrouds, for the brackets it is NOT, the weight of the light will shear it right off along the filament bonding lines. Ask me how I know
I found a friendly individual on Etsy to print the Thingverse brackets for me in PETG instead, which works a treat!
1) Easy 3D printable slide-on shroud, keeps the glare out of your eyes for the tanks in your TV room etc:
Thingiverse link 3D print for shroud
2) Oversized tank bracket, for any tank with a rim:
Thingiverse link for oversized bracket
In real life:
