# Human Eye

Subject Area: Science

Learning Objectives: Students will learn about the anatomy of a human eye. \
 \
Materials Needed: One computer, one Micro or Micro+ 3D printer, and one 250ft 3D Ink filament spool (PLA or ABS-R3 recommended) per 2-5 students. 

Brief Description: Students will print and examine a model of a human eye to learn about its anatomy. 

To Prepare: Students will need a computer that has the M3D software on it. We recommend one printer per every 2-5 students. The Micro or Micro+ 3D printer will need to be plugged into both the wall and the computer. Each printer will need to have a 250ft spool feeding into the external port. A spool holder is also recommended. 

If you need assistance with any of the above please see our guides at support.printm3d.com. 

Lesson Plan: 

1\. Students will go online to <https://www.thingiverse.com/thing:1193457> and download the models. They can either download the complete model, or download it in sections and put it together.&#x20;

2\. Upload the models to M3D software and print them.&#x20;

3\. Once all the models have finished printing, students can use them to examine and identify the different components of a human eye.&#x20;
