Process + Procedure

I already had an approximate design for my project, so when creating the CAD file I mostly had to consider the dimensions and shapes of the 3 rings. I sketched out my design, deciding it would be pretty small, around 2 inches. This choice was because the project is for a keyring, which needs to fit in my pocket. One challenge I faced was that I initially drew the rings as toruses in Fusion360, before realizing that Borromean rings cannot be created out of perfect circles. I then had to figure out how to make oval rings, which I did by drawing an ellipse and using the pipe tool. After making the model in Fusion360, I saved the file as an STL and sliced it with the Zortrax slicer. I printed it on the Zortrax printer, and it took about 3.5 hours. Finally, I removed the raft and supports using pliers and scissors.
