Week 1
Lesson 1
Multi-Color 3D Prints with a single nozzle
This week’s challenge will feature the creation of dual-color keychains that require only a single 3D printer nozzle. By using a series of modifications in the slicer we can tell the printer to pause at specific layers so that we can switch colors and create some incredible prints. 
 Week 2
Lesson 2
Flexible Models
Everyone loves 3D printed flexible models such as the dinosaur Flexi-Rex but are you ready to design your own flexible model? This week’s challenge will involve taking any 2D image and transforming it into a print-in-place 3D print just like Flexi-Rex!
 Week 3
Lesson 3
Wall Art
This week we will learn how to take a small 3D print design and break it into pieces ready to be turned into dramatic wall art. During this week’s challenge students will find a piece of art work and modify the design in Tinkercad to prepare it to be successfully printed in multiple parts. 
 Week 4
Lesson 4
Designing Vase Mode Prints
This week we will create our own designs ready to be printed with a single outer wall known as “Vase Mode” or “Spiralize Outer Contour”. Almost any shape can be turned into a pattern that will look amazing as a 3D printed vase that can be used as a pencil cup, candy bowl or even filled with 3D printed flowers!
