Below is all everything I ended up using to build the final earring, without including the materials, tools, code, and processes I had to bump against to acheive my final product.
As well, it isn't the resources (code, materials, etc.) I would use to make this earring again. For example, my website list is unorganized and hard-coded into the python code, rather than a separate csv or txt file, which I won't do in a v2. I also won't be using any hot glue, even though it's listed in my materials & tools.
Other Materials used
Hot glue stick
Old ugly earring from Claire's
Soldering metal
Tools
Laptop/computer: coding, 3D model print
