Anet A8 Aluminum Brace to eliminate Z wobble

The ANET A8 is a great machine for the money, but suffers from wobble on the X-axis with quick back and forth movements. It gets worse and worse the taller your prints are due to the lack of rigidity in both the design and the acrylic material used.

This brace removes ALL of that wobble. There is zero movement, even when pressing hard on the top of the gantry.

After adding this, one side effect I encountered was getting frequent corruption of the LCD screen. The prints were not affected, but it drove me nuts seeing the corruption on the screen. I eventually narrowed it down to EMI from the X and Y steppers, and resolved it by adding snap-on ferrites to the X motor cable, the Y motor cable, and the ribbon for the LCD. I got them here: http://amzn.to/2krlHv4
