This will allow a RAM Tough Tray II (netbook mount) to be attached to a standard camera tripod. I built it for netbook used when flying rc-aircraft.Tray is available here:http://www.ram-mount.com/CatalogResults/PartDetails/tabid/63/partid/082065077045050051052045054/Default.aspxAfter printing put threaded insert into center hole - available from mcmaster-carr:http://www.mcmaster.com/#90363a028/=fwkz80The four mounting holes mate onto tough tray and attach using the bolts that come standard with the tray - holes are recessed for flush mount against tripod.
