You'll find the design files here
https://github.com/paltatech/std-mainboard

In my computer the 3D files are in
/usr/local/share/kicad/modules/packages3d/walter/step/


2) fusion with color is possible in FC 015 and 016 ... I'm going to send

I'm using part->make compound (in part workbench)
or part->boolean->union (also in part workbench)

Also included in the github repo. The outline was imported from a DXF file
generated with freecad. The 3Dviewer displays it correctly, but I think the
error is in the DXF importer because "Global spread and place" -> "spread
out footprints not already on board" didn't detect the outline, so it
probably has a disconnected segment somewhere and 3DViewer is flexible
enough to display it despite the errors

Thanks
