Z Brace for Ender Extender 400XL

Z-Brace for the ender extender 400XL, requires following hardware:

• M8 thread
• M5 bolts 
• M5 T-Nuts
• Optional: washers 

Additional tip: my Z extrusions were not entirely flat on the bottom side. I used a thin metal plate to compensate for this which can be inserted between the frame and the z extrusion so less tension on the braces. Also use a square tool to ensure the frame is square.
