OK, I converted the .psd to a jpg (which Inkscape will import unlike the psd) and imported it in to the Inkscape breadboard view. Unfortunately when I scaled it so the headers are correct (they are on exactly .1in boundaries) the mounting holes in the .psd are slightly shorter in Y than the measurements in the dimension drawing posted above. I split the difference between the two sets of mounting holes, but the position likely isn’t exactly correct yet. The easiest way to fix that is for you to print out the pcb view at 1:1 scale (preferably on an clear overhead transparency) and compare it to the real board. The header holes should all match exactly, but the mounting holes may be off by a bit. If you can measure how far off the mounting holes are in x and y for each hole I can move them in pcb to match the real position. I have replaced the part posted above with the corrected part. Note as usual, the mounting holes are only on silkscreen in the part, if you want holes on a board you make, in the sketch you need to drag a hole from the pcb area of core parts in to the sketch and set its diameter to 3mm and place it over the hole in silkscreen so the hole will be drilled in the board (if you don’t want the mounting holes leave it as is.)
