About this 3D model

This is a thread guide designed for the Bernina Series 7 sewing machines. It helps prevent the thread from jumping out during use. The model is designed to accept a metal washer for reduced wear on the plastic guide. My wife indicated it has helped reduce the frequency of thread jumping out of the regular rear guide. It is installed using the screw and hole already on the machine. Here are a few of my other sewing models that might be of interest:
