Seiko 5 SNXS watch case opener

Hi. This is my Case opener for the Seiko 5 SNXS series of watches. My particular model is a SNXS73K but I'm pretty sure it will fit any SNXS model. It works perfectly and in case your caseback is on too tight you can apply a 24mm wrench to it. But the grooves make it really easy to grip tight. I printed it with the hexagon pointing downwards and used support structure. otherway round probably also works fine. 30% infil is fine. I used ABS
