X-Carve Drag chain support arm brackets

These brackets are designed to hold a 20x20x958mm extrusion to the back of the X axis of a 1000mm X-Carve. My X-Carve was the old model and did not come with these brackets. I had an extrusion that I didn't use from my side board kit. The side board extrusion was 958mm instead of 1000mm, so I made up these brackets to allow the use of the shorter extrusion.
