Clip for 20mm extruded section frame

20mm square extruded aluminium section is commonly used for cheap CNC routers, especially for kit versions. So I designed this very simple 3D printed part that clips over three edges of the section. I did that for two reasons, the first being that I wanted to use one with two of my frame-end feet 3D prints (click here to read more) to make a stable tri-point support to reduce vibrations when routing. Secondly though, it’s just a useful thing to have to glue to anything I want to fix onto the frame while still being able to remove it later (e.g. bit holders or cable tie down pads). If you’d like to 3D print your own, just click here to get the STL files on Thingiverse.
