This model's fully articulated at all joints, including along the spine. It sits comfortably on your hand and also likes resting on things.
I've uploaded both the standard and NoMagnets.stl/obj files so you can choose to print either the version with 6.1mm x 3mm holes in his feet and head for small magnets, or not. I found cheap neodymium magnets from Amazon which fit perfectly, so it lives on the fridge! (Link below).
Image attached is 0.2mm nozzle with 1.75mm PLA, 40% infill. I recommend printing full size to avoid fragility issues with the joints.
