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 ...

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 > > thank you > Maurice > > On 19/08/2015 17.13, Marcos Chaparro wrote: > >> About the USB connector, don't follow the original part from the >> manufacturer, it took me a while to align it. >> >> Here is the step and vrml of that connector.
