Improved bottom half for The Butterfly E3D mount Free 3D print model

The butterfly mount is great, it's lightweight and easy to print, however I fount the lower half ("wings" of "the butterfly") which is the part responsible for clamping not quite convenient.

So, I made the "wings" wider to hold the main body of E3D instead of just holding the metal bowden connector, this should make it stronger and easier for maintenance.
