ProtoXtruder 2.0 Skeletonised front and rigid back

I like it when I see the movement of gears and filaments. So, changing the front was just decorative. The back was made tougher, perhaps unnecessarily stiff. I also changed the tolerances for the gears a little bit. This design has been tested with TPU 95A, and everything works perfectly. P.S. Please leave a feedback if you think the design could be enhanced.
