I have been 3D printing since March 2017 and I am 16 years old. I am interested in creating useful prints and home decor. I am also interested in computer programming. I am still a beginner/intermediate at CAD and a high school student, so I create designs during my leisure time. I got into 3D printing when my school started discussing and showing us their printers. At school we got some elite printers: The Prusa i3 mk2 and the Lulzbot Taz 5. I also got motivated by YouTube videos as well.
