Can you help me ? The aquarium is the one I have designed to be adapted to external filters. I was able to do this in the TinkerCAT program for the project work that was given to me at school. I do not know much about modeling. The upper water outlet of this module can be removed and the part thickness should be 3 mm and the spiral part inside it should be connected to the water outlet area. Once you have arranged the project, do you send it to adallar71@gmail.com? What program do I learn and can I make such models? Thank you from now
