Simple cable guide to prevent cable abrasion behind PSU on the Ender 3 V2. Mounts directly to the end of the 80/20 extrusion in to the threaded holes using M5 screws of your choice with up to a .35 diameter head. I printed it in PETG with 20% infill, 240C hot and 80C bed, 60mm/s. Attached my gcode. Orient the print so one edge is on the bed and print without supports.
