Seiko Watch Case Tool

thingiverse

I made a tool in OpenSCAD to remove the back of my Seiko watch with a 32.76mm case. It worked great for me, even at 50% infill. Here's how I designed it. The design is in OpenSCAD format. difference(){ cylinder(h=12,d=32.76); translate([0,0,-1]){ cylinder(h=14,d=24); }; }; for (i=[0:6]){ rotate([0,0,60*i]){ translate([32.76/2-2,0,0]){ cube([4,2,14]); }; }; }; translate([-5,-30,0]){ cube([10,60,5]); };
