Anet A8 - Rear Back Frame Splitted (Telaio Posteriore)

Hi, this is the rear frame for Anet A8 for those who have broken the original one.
It is too long to be printed in one piece so i've splitted it in two parts with a male/female junction.
I've designed it 2mm thicker to make it strong...if u like u can scale Z direction inside your favourite slicer to make it like the original (8mm).
I've also closed the two holes where the plate rails are fitted.
Also add an extra triangle shape to both X sides for better support with the rest of the frame.
