Watch back case opener, 19.6mm, 6 points

Universal (not brand specific) watch back case opener for 6 point screw back with 19.6 mm diagonal distance between the notches (so ladies sized watches). Can also be used for notches with a slightly small diameter - in the picture the Orient watch at the right has 19.6 mm distance, while the Seiko watch at the left with 18.5 mm distance also can be opened and closed with this opener! Here print in Kingroon gray PLA using the generic PLA profile (0.2mm, 15% infill, 2 walls) on an A1 mini.
