2020 cable guide (OpenSCAD)

I had a need to keep some 230v AC mains cables out of harm's way in my CoreXY printer, so I devised these little clips. They are based on a simple L-clip written in OpenSCAD that I *think* I picked up on Thingiverse ages ago but, unfortunately, I can't find the original design - if anyone recognises the basic idea then let me know and I'll credit its designer.
They clip nicely onto Motedis 20x20 profile extrusion.
