Garden Edge Connectors for Technoflex EcoBorder

I could not find connectors to make a clean connection between Technoflex EcoBorder garden edge sections and I did not like the look of simply cutting the edge at an angle so I designed my own using OpenScad.

I tried to fully generate the edge profile using primitive geometric shapes in OpenScad but I struggled to come up with an exact match for the bottom tip.

After multiple iterations, I gave up and I ended up tracing the contour of the edge on a piece of paper and scanning it.  I then generated a clean and exactly matching shape by importing the scan into Inkscape and tracing the profile using the pen tool and Bézier curves.

The final and clean SVG shape:

The Inkscape GUI was showing 71.15 as the width of the object.  When importing the SVG in OpenScad, I wasn't getting the right scale until I specified the DPI.  Also, when using the width value from the Inkscape GUI, the geometry would not render when scaling up the imported SVG and attempting to rotate extrude it.  It turns out that the width shown in the GUI is not exact and I was able to calculate the real one using the pixel width found in the SVG file:  268.91473 pixels multiplied by 96 DPI (pixels per inch) and divided by 25.4 mm per inch equals 71.1503556 mm…
