I've been happy to see LEGO came out with a way to display the myriad of minifigs out there:
And I was also very happy to find that I can hang these on the wall with the convenient eyelets on the back:
Yet despite earnestly searching I can't find anybody that has created a template for installing these. How far should the screws be apart? How far apart should the holes be if you want stack them like so:?
I'd prefer a printable template that I could drill through, but if you have measured these accurately that'd be a good start.
