A client of mine asked me for a 3D printed doughnut, I could not find a model that satisfied what I was looking for, so I decided to make my own model of it. The client cancelled the project, but I finished the model anyway. I did it the same way as for my One Ring model, drawing fake level maps of the donuts, and plotting them on a toroidal coordinate system, using MATLAB R2016a. They are intended to be as realistic as possible, however, I didn't have a donut on hand to use as reference when modelling, they were made by guessing their sizes, curvatures, shapes, etc, so that some details may be wrong or exaggerated.

I spend part of my time making these models, letting them available and free for everyone. If you want to support my work, you can contribute with me by donating to this PayPal account.
