About this 3D model

I wanted to build a Mini Quadruped but they all seem like they have no grip and fall over. I really like the Quadruped design by TheCase and it seems to have quite a few adaptations by a few other members so I could make a few mods down the road if I wanted to so I downloaded it and made a quick mod of my own to use with Sugru as the feet. I got the idea from the Sugru FixBot where the notches are on the finger.
