New extrusion to join / stiffen X-axis makerslide?

[JohnScherer]

@DavidSohlstrom did some work on this very issue and talked about it in this post. I’ll be making the same mod to mine.

Width of gap X axis makerslides

Could some one measure the gap between the makerslides on the X axis. I am thinking of sandwiching a piece of steel flat bar between then and make it tall enough to just clear the top of the carrage and drop down and just clear the bottom on the carraage. Thank you Dave
