FYSETC E4 3D printer Controller

UPDATE: My pull request on the fysetc E4 hardware repo was merged, the official model in the repo is now identical to this one. From here on out, the repo is a better source for 3D model, as it's subject to further revision that could make mine obsolete. 3D model as found in the FYSETC E4 github repo, except with missing mounting features and components added. Updated ecad including library project files with inserted 3D models can be found in the comments, grabcad doesn't seem to like Altium designer source files in the main project page apparently. .
