Unfortunately the bottom line is that unless someone else has modelled it you have to get to grips with Wings. Fortunately that's not too difficult. The way I approached this was firstly I just adjusted the scaling parameters in kicad of a similar existing component model. That will almost certainly mean you end up with the wrong number of pins, so when you're fed up with that that you can progress to doing the scaling in Wings and adjusting the number and position of pins as necessary. Then you can move on to creating components from scratch. Don't forget that all you really need is a box of sufficient size to indicate the dimensions of the body, and something to show the position of all the pins. If you've done everything correctly twice, your Wings model will fit on the footprint in the kicad 3D view - a very useful check of your work.
The units used by the existing kicad Wings models are Imperial, so when published dimensions are in metric only you either have to divide them all by 2.54 (tedious), or you work in Wings in metric (scaling as required existing models). The resulting model will then either have to be scaled back to Imperial, or you can do the scaling in kicad. Regards, Robert.
