My dust shoe wasn’t damaged because it was sitting on the table top. It was most likely damaged from normal usage and where it cracked was the narrowest, weakest area. Luckily the 3D printed part underneath appears to be more flexible and holding it together until I can cut another.
Good idea with putting a metal plate on the front of the table to hold the dust shoe. I usually just flip it upside down and put it on the opposite side of the gantry mount.
