Used in commercial embroidery machines to add space between needle bar and hook cover. Recommend using Nylon, or try polyfex this is a very thin build just .5mm scale Z as needed to add space. I consider this a temporary fix but should last for a while do not use in machine with plastic needle bar parts. You need to cut at center of each hole so to fit into needle bar.
