About this 3D model

Replacement bracket for the z axis nut holder in a Printrbot Jr. Reduces the amount of play the z axis nut had to a minimum. Replaces the original threaded rod and nut with stainless steel M8 threaded rod, two nuts and a spring in between the two nuts. Ideally you should use brass nuts. But I used stainless steel nuts since they were available and work just fine.
