My Printrbot had some trouble with the arm joints melting together during printing so I opened them up a bit.
Increased the shoulder hole's diameter by 0.25mm
Increased shoulder poles length by 0.5mm (and shifted arms 0.25mm out to recenter)
Increased the elbow hole's diameter by 0.25mm
Decreased each forearm width by 1.0mm (removed middle 1.0mm and merged 2 halves together)
