You might need to scale this model to fit your printer, and reasonable scaling should produce good results.

You should probably print this with support material enabled, although if you modify the arm angle in blender you might be able to get it to print without support.

I removed my support up with a pair of wire cutters and did some smoothing with a nail file and a Rotary Tool. Be careful on the hands as the fingers are rather fragile.

I Printed with ABS White plastic

Be warned this model is not open scad friendly out of the box; blender is the recommended editing software for this model.

Yes, I am aware that one of the hands is at a questionable angle, this is easy to fix in blender; however, I like to call it an artistic signature.

Likewise, this model could use some more refinement and segment scaling and smoothing to look better. Nevertheless, this model was designed based upon the fact that printing acts like a mechanical filter that will remove most of the joint imperfections; However, feel free to clean it up in blender.

I like to run my printer slow and steady since my print deck has a tendency to dance around a bit so your configurations will vary.
