Getting Started in Tinkercad

Tinkercad is a FREE, easy to use, web-based, 3D modeling application geared toward kids in K-12, but anyone can use it to make handy and fun objects that can be printed using a 3D printer.

This Getting Started Project (PDF) walks you through the steps to make a boat, complete with fun cutout shapes for windows. Print it out, or read it on-screen, and start building!
