Simple cable/knot device to tie something onto a keychain.
Design is inspired by those soft gel holders for small hand sanitizer bottles. It usually consists of a lengthy soft material with knots 2-3 inches apart which can hold in place by inserting it in a form fit hole.
I printed this in TPU with an Anycubic Kobra but you might be alright with other material since it's fairly thin.
