Is there any way to make pre-made flexi joints and copy and paste them into models?

Im gonna start making mini-flexi animals for my girlfriend to 3d print. I’ve made a few already but I have to make each joint by hand and it takes a considerable amount of time. Theres gotta be an easier way where I can just premake the joint, and import into each project and use it.

This is basically what im trying to achieve. But not in zbrush. Surely there is a way in nomad! Im still fairly new, by the way.
