Floating Aquarium Ring

I designed these floating rings to help create holes for light to go through as the surface of my aquarium is covered in floating live plants. This is a good way to see in, let light through and creates a spot to feed the fish. I have made the rings at 20cm, 15cm, 10cm and 6cm. Original files have 1.8mm holes around the edge that will fit a scrap piece of filament to make chains. 

Edit** Upon request there are now versions without holes to decrease chances of it not being water tight.

Hope this is useful to other enthusiasts!

Easy print, use no infill if possible. This keeps it light weight and fills the cavity with the most air possible.
