E3D Hotend Mount

I designed this part for my printer to improve the printing quality, reducing the backlash. It's a more rigid piece with more contact surface. Worked fine to me!
Recomendation: Print with supports, it makes tighter the hotend installation.
Size: 12mm inner diameter and 16mm outer diameter.
