    Very thin cross-section at the point in the top forearm where yoke cuts-in to hourglass shape combined with mounting holes for Dynamixel.  See part:

    Suggest:

    Making fork arms thicker and/or broader,

    Eliminate hour-glass taper inside,

    Reinforce forks with long bolts or metal rods.

    I have taken the liberty of editing your post to update the link (we just modified our github repository so the link was broken. It is now located in the archive section).

    Did you have some problems with this part ? (such as breaking it) From our many tests with this v1.1.0 part we had no problem while using the robot.

    The shape was made like this to have some nice aesthetic. Thanks for the suggestion though, I think this can be helpful for other v 1.1.0 users, in case the part shows some signs of weakness.

    Also, one important note when assembling this part : make sure not to apply too much pressure with your hand, that’s how you break it. If you only apply pressure on the axis 5 shaft when the motors are plugged, this will be ok.
