I will be teaching you how to make a 3D printed i-phone 5c case. First step is to find a file of and i-phone 5c case, you can do it with any other i-phone case if you want to. To find a file the first thing is to make sure you know what kind of printer you have, for me I had to search for an stl file. Once you have your file you go in and fix the settings, click add printer and add your printer into the file. Now your ready to print, go to your printer and then get a flash drive and download the file into the drive, after you start printing you case the approximate time for a Cura Ultimaker was 3 hours and 13 minutes. After that your done and you have your phone case. This project relates to engineering because your doing the engineering steps.
