Added 3D for Jadak Thingmagic M6e-Nano

Source: KiCad/kicad-packages3D-source#266
Footprint: KiCad/kicad-footprints#2125
Datasheet from Jadak requires some data (name, email, etc) before downloading the datasheet. See user guide at:

Thanks for creating a pull request to contribute to the KiCad libraries! 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 footprints is very useful
• Was the 3D model(s) created in a mechanical modelling program?
• Source files (or scripts) have been contributed
• 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 against mechanical models

@cnieves1 some feedback:

• The data sheet link appears broken. It redirects to the Jadak blog

Feedback for maintainers:

• .step and .wrl load and look good
• Overall part dimensions match drawings (footprint is in review in another PR)

I'm afraid Jadak requires some data (name, email, etc) before downloading the datasheet. See user guide at:

@cnieves1 if you could update the links to point at the spark fun source that would be helpful for the next person. Otherwise model looks good!

Done, here and in footprint and symbol PRs.
