3D model description
I teach vectors in my math classes and with distance learning in Fall 2020 I found that I needed some vectors that would work well for display through my webcam during my virtual online classes. Bright colors easy to identify make them more useful too. I like to think of the small ones as "unit vectors" since those are important for what we do.
Once they were rolling around on my desk, it was clear that I needed a way to manage them and with a little inspiration from my daughter, I designed a holder to display my set and keep them at reach during lessons.
3D printing settings
Vector cone is approximately 38 mm in diameter at the base. The long vector is 200 mm long and the small one is 100 mm long. The Holder is 41 x 167.25 x 25 mm.
I printed the vectors pointing down with supports. The tips aren't perfect, but it was much faster than printing them with supports along the entire length. (I didn't want to print them laying down since I thought the layers would then look somewhat unnatural for the shape, but you could certainly try that too.)
I printed with 0.3 mm layer height and 10% infill.
For the Holder, I printed 0.3 mm layer height and 20% infill. No supports. No raft.

I am a high school math teacher and 3D printing hobbyist. I have been 3D printing since 2017 and enjoy making things for my classes and my own children and home in San Diego, California, USA.
I have a 3D printing sub-site abbymath.com/3DPrinting. See my video on YouTube and my user story written and published by Simplify3D. I design with Mathematica, CorelDRAW, Fusion 360, and Tinkercad. I love my MakerGear M3-ID and my Palette 2S Pro. I have a Monoprice Mini as well.
