This is a display pillow for a 3d printer nozzle. After I retired my irreparable Ender 3, I designed and printed a pillow for the nozzle that had served me well for years, so it can finally rest. It should be sized for any standard 1.75mm printer nozzle. It sits comfortably laying on a flat surface, but I designed it to also be able to be put at a slight angle, shown in the last picture.
