Work is my own, done with FreeCAD, based on the mechanical drawing at
http://suddendocs.samtec.com/prints/sma-j-p-x-st-em1-mkt.pdf

Some of the dimensions aren't specified in the drawing so I guessed. I
don't have this particular connector but a very similar one so I wasn't
able to measure.

Thanks for creating a pull request to contribute to the KiCad libraries!
Remember you must be the legal owner of the 3D model! Models downloaded from a manufacturers website cannot be accepted.

To speed up integration of your PR, please check the following items as you complete them:

  • A screenshot of the model(s) aligned with KiCad footprint(s)
  • Source files are contributed on the apropriate location
  • Step model submitted in 1:1 scale
  • WRL model submitted in 1:2.54 scale
  • 3D model alignment checked against KiCad footprint
  • WRL model uses correct material properties
  • Geometry check performed on the model

Be patient, we maintainers are volunteers with limited time and need to check your contribution against the datasheet. You can speed up the process by providing all the necessary information (see above).

I guess "Geometry check performed on the model" means Part -> Check Geometry in FreeCAD? If so, did that. If not, please link instructions and I'll be glad to do.

A couple shortcomings I know of:

  • the geometry of the threads is not exactly right. I'm no mechanical engineer and researching exactly what the geometry should be seemed like too much work.
  • chamfers and a few similar details are omitted. I figured they'd just slow down rendering.
  • it looks like this connector is designed for an interference fit: the center pin protrudes down a little lower than the legs that sit on top of the board. I also wasn't sure exactly what board thickness to expect, so the Z axis positioning is just eyeballed.
