About this 3D model

Hello everyone, Here is a handy item in sea water aquarium to fix your cutting support. I imagined this model because each time, my optical grid detach from the glass of my aquarium because to fix with suction cups, and also for a discreet and aesthetic rendering. Description of the object: These are hooks that you install on the edge of your window and comes to fix with your small optical clips. And keeps your cutting to 10cm from the edge (see photo description)
