Molex 4 pin plugin

I’m looking for footprint and STL model for:

For 3d my first step is 3dcontentcentral.com
For footprints, look at kicad built-in library, that’s some pretty basic part. Otherwise searching online will take you the same time as creating one from scratch.

EDIT: and not STL, but you want STEP

For the 3D model, you can go directly to molex and download their model. I found it on the English site here: https://www.molex.com/molex/products/part-detail/pcb_headers/0022057048
There are many formats that you can choose to download in, and apparently there are two STEP formats. I appeal to those on this forum for guidance for which of the two (AP203 or AP214) would work better. I did download one of them (I actually forget which one, but I think it might have been AP214) and loaded the resulting .stp file into FreeCAD without issue, but I don’t know if FreeCAD is in your workflow.

This is not avalibale as part for KiCAD?
I need omron B3F-4000 button
https://pl.farnell.com/omron/b3f-4000/switch-flat-spst-no-0-05a-24vdc/dp/176434

Any repository with this type of parts?

It’s just a common 6x6mm THT button, SW_Push_6mm or one of the variants in KiCad footprint libraries (checked with KiCad v5.99). Just make sure that the pin numbers match with the used symbol.

EDIT: No, sorry, 4000 is a 12mm model.

It is possible to import all of this parts automatic?
Why are you recomend me KiCAD v5.99? In last version no molex FAN 4pin and this button

I don’t recommend the unstable development version 5.99, I just mentioned because I had it at hand and looked at the libraries. The stable version may have a bit different collection of components.

A generic switch symbol is OK for the button and you should learn how to make your own footprints anyway. Learning it takes some time but it’s not too difficult and when you know how to do it you could create a footprint for it in five or ten minutes.

Or you can use a footprint for a similar model, https://www.snapeda.com/parts/B3F-4050/Omron%20Electronics/view-part/?ref=search&t=B3F. But normally even finding and dowloading and importing that to KiCad would take about as much time as creating one from scratch.
