Mr. Rockboto is not only a fun print-in-place figure but it is also a very useful calibration tool.
He has 14 functional joints with different orientations, couplings, and tolerances. The tolerances range from 0.2 - 0.5mm and allow you to test the minimum clearances your printer can produce and still achieve print-in-place movement.
Each limb is labeled with the tolerances of their joints and all other joints have a 0.3mm tolerance. It might take a little (just a little) bit of force to break them free any more and you risk breaking the robot.

No support! No brim!
The point of the Benchmark Bot is to find the best parameters to make it function, therefore it is difficult to recommend any settings.
That being said, I used the following parameters: 0.4mm nozzle, 0.2mm layer height, PLA, 3 walls, 4 top/bottom layers, 10% infill.
