hi everyone, This time, i've built a automatic knife from A to Z.First i started to draw the knife design and thought about the opening mechanism. Then i thought about how i will build it and with wich materials. then i drew it on solidworks with the colors i want. now, i 'm ready to built it, it will take some time but i want to try something newas you can see, i understand more how to make rendering but i can't find any proper background. If you got some advices, feel free to give me some :)
