Aquarium floating barrier for duckweed

cults3d

I created a floating barrier for a close friend. The two edges at each corner are wider to ensure they stick to the walls through capillary action. This way, duckweed won't cover the aquarium's surface, and your fish can find shelter or lay eggs beneath the lenses. The barrier's wall thickness is 1.2mm, which is three times the diameter of a 0.4mm nozzle. I designed this floating barrier using FreeCad.
