Biography[edit]

My name is Noah Stewart and I am a Junior at Principia College in Elsah, Illinois, majoring in Global Studies. I am orginially from Dresden, Germany, where I grew up and graduated high school in 2017. At Principia College, I am engaged in a variety of activities including being the Co-Director of the 2019 International Perspectives Conference, being the student manager of the Social Assistant Team, and playing the Violin in the College Orchestra and String Quartet.

Prints[edit]

Preliminary Print: Hufflepuff Crest Firstprint.jpeg I got this model off of Thingiverse from user kakhbarth (CC BY 3.0;https://www.thingiverse.com/thing:2384939). To fit onto the Jellybox build plate and for a faster print, I had to scale it down to 40%. I left the print and extrusion speed unchanged. However, because this has quite intricate designs and I scaled it down, I lowered the layer height to 0.1 for maximum detail. I used a skirt to make sure there was no warping. I did not change the number of shells, fanspeed, or infill.
Replacement Part Replacement.jpg This is the feeder yoke replacement part. I got the design of off the Imade3D website. As it is not a very detailed design, I kept the layer heigt at 0.3 and infill at 20%.
Brandenburg Gate Brandenburg.jpeg This is a fun print of the Brandenburg Gate that I made now that my printer is working well. I lowered the layer height to 0.1 to make sure all of the details came out well. That worked out even though the horses pulling the carriage ended up looking like sheep. That is mainly due to the fact though, that I had to scale the model down. I got the design from vandragon_de on Thingiverse.com which is licensed under the Creative Commons - Attribution - Non-Commercial - No Derivatives license
Church of Our Lady Frauenkirche.jpeg This is a print of the Church of Our Lady (Frauenkirche) in Dresden, Germany. I got the design off of Thingiverse from user vandragon_de and is licensed under the Creative Commons - Attribution - Non-Commercial - No Derivatives license. For the print, I set the layer height to 0.2 and infill to 20% as this was a very detailed design. Additionally, I added a brim to minimize warping as much as possible.
Bench Thing Benchthing.jpg This was my first design using FreeCAD. The design was made by me following the class instructions. I kept the layer height in Cura on 0.3 and the infill on 20% to save time. It would have been good to print a brim instead of a skirt as I ended up having some warping at the bottom.
Penny Trap Pennytrap.jpeg This is my first design using OpenCAD following the in-class instructions. To make the print go fast, I set the layer height to 0.3 and the infill to 20%. Additionally, to minimize any warping I started the print with a brim. This little penny will be trapped forever...
Rock Wall Hold Design RockWallHoldNoah.JPG This is the rock wall hold I designed using the design from Thingiverse by mfarson licensed under the Creative Commons - Attribution license. I used OpenSCAD to alter the design and make my rock Wall hold unique. To print this design I would recommend using a large layer height and 20% infill as this will provide the most amount of strength to the hold.
Octahedron and Cube Educational Aid Octahedron.jpeg This is a design to print an octahedron and cube shape. It can be valuable for classes in crystallography to visualize the shape better. Crystals are used to help teach about symmetry. This shape is a physical maniuplative that can be used to help teach those concepts. This is a basically free alternative to the models that are available online which all cost well over $100[1].The blender file needs some fixing. However, the stl file is fixed with the help of netfabb and printable.
iPad Stand Corner Pieces Corners.jpeg This is my design for the science project assignment. They are corner pieces for an iPad stand that holds the iPad in place inside the frame. The iPad stand in question has the model numbers SKU IPDLMSSVL3 and GTIN 810878025681[2]. If one were to lose even only one of the corner pieces, one would need to buy a whole new stand for $99 to have a new functioning stand as the company does not sell any replacement parts for it. The STL files for the corner pieces are available on NIH[3].

Reflection on Participation in the Open Source Community[edit]

I have to say that I am fairly new to participating in the open source community. However, as soon as I learnt about it I was fascinated by its innovation. I believe that it is another step in the long-term development of us as a human species coming closer and bridging our differences for the greater good. Keeping innovations and ideas secret is done in order for one group to reap the benefits of it while another does not. As we realize that there is more to this world than competition and the growth of one's own wealth and status, it becomes clear that we must work together and build off of each others ideas to achieve the impossible.

I got to experience the power of open source working by building a Jellybox printer by myself. The community around these printers and the innovations it makes was extremely helpful when, at one point, there seemed to be a missing part which was included in newer generations of the printer but not in the older ones. Thankfully, someone had created and published the design for the part that was needed and we simply printed it with another printer.

In the future, I think that the concept of open source can be expanded to include industries and spheres beyond manufacturing and software. What would be possible if every economic industry and intellectual source were available to anyone? There certainly are clear benefits but in hindsight maybe also some drawbacks of such an environment. Time will tell where the open source communities goes and which blessings it will have on the world.
