I created two drain snakes. I've used the short one on my own sink. Because it's circular you will need to print it in nylon and then straighten it. I used Taulman Bridge Nylon. The longer one may need to be thickened. The short one turns out to be like 18 inches long which was more than long enough for the job. Nice thing about Nylon is that if it gets stuck and twisting doesn't help you can always just pull because the nylon will NOT break, the teeth will just bend.
