Updated leg design for mk2 servo

Since the mk2 moteus servo has slightly different dimensions and a different mounting pattern than my original, I needed up update the full rotation leg design to handle it.  The basic concept is the same, except for some in-progress work on the foot design which I’ll write up later.  The only significant changes were that because of the mk2 design, access to the power and data connectors is much easier.

Here’s a brief CAD snapshot:
