ENGR242: Hanna Farson

• My name is Hanna Farson and I am a junior at Principia College. I am a French and History double major and I am taking ENGR 242. I am very interested in languages, I have been taking French since I was 5. I also took two years of German in High School and had introductions to Flemish and Hebrew in Elementary School. I have also joined Russian club at my college, since a class is not available. In the future I would like to continue using the languages I have learned, however, I have not yet decided in which capacity I would like to do that.
• The Open Source Movement is a movement to freely share designs and allow people to build upon other designs. This allows information to be easily accessible. I really like this movement because it allows people to build upon other designs which results in extremely efficient products being available to everyone. At the beginning of this semester I built a Jellybox printer, many of the parts for Jellybox printers are openly available online meaning that I can print spare parts to have on hand if something breaks. I don't see myself continuing in STEM in the future, however, I'm sure there are ways that will be able to incorporate the concept of Open Source in my future once I figure out what I'm going to do.

My Prints[edit | edit source]

Picture	Description	Information
	This is a human shaped phone holder/stand that I printed for an assignment	I found this print on Thingiverse and it was posted by byctrldesign. Link: https://www.thingiverse.com/thing:525066/files.

	This is a over the door hanger thing. You can print as many hooks as you want to put of the arm. You can also flip the direction of the hook to have it hang over the door or hold stuff	I printed this for about $5, commercial equivalents that I found were $20-$25.

Abstract[edit | edit source]

1. I created these files of construction blocks because I have fond memories of playing with similar toys and want to give other children the same opportunities for much memories. Also, research has shown that having opportunities to play creatively is important to childhood development, and construction blocks are a safe and fun way to do that.
