I designed this to enable me to attach my DIY Nikon GPS ( http://cyrozap.com/2011/08/13/diy-nikon-d5100-gps/ ) to my camera so I don't have to hold the module while trying to adjust my zoom.I haven't tested this with the flash yet, so there might not be enough clearance between the GPS and the flash to allow you to use the flash.Print (as it's shown works fine), then try to fit it in your camera. If it doesn't fit, do a little sanding until it does. Use either velcro, strong double-sided tape, or superglue/epoxy to attach the GPS module to the hotshoe insert.
