I plan to 3d print all the leg details. I have a Flashforge Creator Pro. These files are available on the Astromech.net wiki. They're already sliced to print on small print beds.

The first leg cuts were rough but with a little trial and error I have a full set of legs.

The next step is gluing these together. They're just dry fit at the moment. I used a 3/8th wooden dowel as alignment pins. There's a sheet of aluminum cut into the ankle section for added support. I've seen images of cracked and broken droid ankles. This can lead to damaged droids or worse, injury to people around the droid.
