3-D Express Printing Experience

Trial proof of concept

Your Second 3-D Express Session: Learn Tinkercad

This 3-D Express guided practice build upon what you learned in your first 3-D Express session. In this session you will learn how to build a simple model of a cork pal animal by "copying" the model held in the file using the free software Tinkercad. 

You will also learn to search thingaverse a repository of copyright free 3-D models in .STL files.

Be sure to follow the preparatory steps listed in the beginning of the handout.
