Dummy 13 Bird Legs and Feet

A set of bird-like legs and two kinds of posable bird feet—anisodactyl (3 toes front, 1 back) and zygodactyl (2 toes front, 2 back)—for Dummy 13. The new calf attaches to a regular thigh using the base Dummy knee, while the tarsometatarsus (smallest leg "bone") attaches to the calf with a modified backward-facing knee joint (a real bird's ankle or "hock"). This joint can be difficult to remove without pliers, so make sure you've got it the right way around (three points facing the back, two rounded parts facing the front) the first time.

Note: files are scaled to 150%, and I only tested at this scale. Assume the legs will be super fragile if printed any smaller (but if you want to try it at base size, you can scale these parts down to 66.67%). As structural parts of the Dummy, these should be printed in PETG.

Edit: added a 100% scale version that contains all the leg pieces and both types of feet in one 3mf—it should fit a “normal” Dummy 13 figure. Make sure your PETG is dry and your print bed is clean. 

Remix: For the legs, I took the calf and forearm “bones” from the original Dummy 13 V1.0 model and replaced their rectangular middles with thin cylinders while narrowing the geometry around each joint. For the new “hock” joint, I removed the kneecap stud from the Dummy 13 knee frame. For the two types of feet, I copied and attached the toe joint on the foot armor to the back of each foot and modeled front and back toes with the appropriate attachment points.
