About this 3D model

I have installed the "BQ bed expansion kit" in my BQ Prusa Hephestos and, after that, I was thinking about it needed a best stability. There you have the two releases of my feet for BQ Prusa Hephestos, since the most simple version 1.0 toward the extended version 2.0. All of them are totally functional and, as you can see in the photos, I have tested them in my 3D printer.
