About this 3D model
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.
