Clip/foot for CNC 20mm section frame

I made this small clip as a support foot (with a rubber foot stuck underneath) for my 1610 CNC router, with two other corner feet to make a stable tri-point support. It could be useful too as a quick start for a project to mount something onto 20mm-section frames on any CNC machine.

I've included the OpenSCAD file in case you need to modify it, or adapt it into your own project. So the model would be flexible enough to clip over the frame properly it's able to slide along the aluminium section.
