Tinkercad is a website where you get to build things in 3D. I’m not a master at it though. Although I’m not that good at building, I have created a couple of designs I might want to print out. It’s awesome that my school has a 3D printer so that we can actually print something. If you want to start building on Tinkercad type in www.tinkercad.com and create an account by using an email and password.
