• 20% infill, pattern: support cubic
• Top & bottom fill pattern: concentric
• Slightly oversize modifier cylinder around center post and through the handle, with 100% infill, pattern: aligned rectilinear, to give center post good grip to  the handle, all the way through to the other side outer surface.

I recommend printing this in orange, for that color's reduced ability to be lost, unlike Oras original grey metal key, which, being a real Houdini at that, necessitated this whole design in the first place.

Customizing

In OpenSCAD you have following parameters to play around with:

$fn=50;                 // smoothness
key_height = 6;         // center post height
key_thickness = 14.5;   // center post diameter
keyhole_size = 6.2;     // center post square hole size
recess_depth = 6        // recess of center post, use 0 for no recess
recess_width = 22       // clearance diameter around center post
handle_base_width = 60; // handle size in width
handle_thickness = 5;   // handle size in height
number_of_cutouts = 5;  // how many cutouts in handle
cutout_size = 25;       // handle cutout diameter
cutout_distance = 25;   // cutout distance from center
edge_roundness = 4;     // handle edge roundness
