I’m a little confused with the elbow joint. Was there ever a left-hand version of elbowshaftgearv1 ? I seem to have printed both a left-hand and right-hand version.

Do the gears for the elbox join go on the inside or the outside of the bicep? Or are they on the inside of one and the outside of the other, making both biceps identical?

robcap has left and right hand versions? But do we still use the same part for elbowshaftgear for both left and right arms?
