Boston Dynamics Atlas v2 Robot. Posable action figure 3.75-Inch-Scale.

Most parts can be printed without support.

Parts that do need support are:  hip_L  hip_R  biceps_L  biceps_R

Joints are very tight and may require filing / sanding to fit.

The print you see is from my very old printer with a .4 mm nozzle.

There is a high likelihood of parts breaking, so bare this in mind and that the friction joints will wear loose.
