About this 3D model

For a friend, I made this floating barrier, the two sides making the corners have a larger surface in order to adhere to the walls by capillary effect. With this, the duckweed does not invade the surface of the aquarium and your fish can hide or lay their eggs under the lenses. the thickness of the walls is 1,2mm ie 3 times the diameter of a nozzle 0,4 mm Design realized under FreeCad I designed this floating barrier for a friend of mine. ー
