I made two versions as on the right the installer put a bit of support to compensate for the slightly sloping ground. I printed with a 0.6 nozzle but you can of course also print with a smaller nozzle. If you would like to optimize you can open the file in FreeCAD and change the thickness to 0.86mm to make exactly two lines or 1.67 for four.
The author marked this model as their own original creation.
