NEMA 17 motor Insulator Pattern - Cork

Simple pattern for producing NEMA 17 motor insulators from sheet materials like Cork. Large diameter is intended to be cut with pointed very sharp exacto knife (be careful!!!!), while 4 small screw clearance holes are meant to be punched using a typical hole punch tool (~3.4mm or 1/8" hole punched).
