Non planar 3d printed Velcro

I wrote a python script to generate a piece of Gcode to add to the file to be printed.
A number of settings can be changed to suit your own designs.
the code is still being written to have better results but I put you a copy if you want to test and possibly improve the test.

Here are the editable parameters.
The X,Y and Z correspond to the coordinates where to start printing.
"e" is the last value of the extruder before adding the gcode.
"S" is the nozzle travel speed.
"f" is the amount of filament that will be extruded per mm.
"l" and "w" correspond to the length and width of the surface where to print the velcro.

The project is still in progress and the velcro does grip well yet.
