I found out about this contest a week before it ended. At first I decided not to participate. But then I changed my mind, decided to try my hand at it, I told the girl who sent it to me: "I will be the winner!" In a week I modeled 12 doorknobs and printed them. I checked the ergonomics and they were excellent. A total of 161 works from 31 participants were submitted to the competition. Later I found out that I won. My design will be manufactured at the  LineaСali factory. I cannot show the winning design. But I want to show other works submitted to the competition.
