Hello, I’m [Your Name] from China. I want to use 3D printing to create a hook for hanging kitchen utensils. Here’s a simple sketch I drew on my iPad. These are my kitchen ladles, spatulas, and utensil rack.

Right now, I’m using some soft hooks I bought on Taobao, but they move around a lot because they’re flexible, which makes them inconvenient for daily use. So, I want to customize a row of 7 hooks to fit my specific needs using 3D printing.

I have a Xiaomi 3D printer, but so far, I’ve only printed some cute figurines from models I downloaded online. Through this course, I hope to learn more about 3D printing and successfully create my own design by the end. Thank you!
