@Shack is updating the 3D STEP & VRML CadQuery library @github (the one you are a contributor too), aligning the name to kicad libs...
the models are coming from scripted routines based on parameters as in the referred data sheet of the manufacturer, so accuracy should be very good
quality is improved because Materials are implemented as per @kammutierspule materials doc
VRML file size is already much less than Wings3D one
STEP file size has been optimized, compared to the previous models
Ooops, I thought that we were going to be paid with a lot of cookies for offering this gift
FCStd file is not necessary, because the source are a script and a parametric file
