just do like vladimirjp told - put both scripts - the MJPolyTools and the MJPolyToolsUI into your scripts directory, update your userSetup.mel (type -> MJPolyTools which is also in your scriptsDirectory and restart maya. I case I misunderstood and you need the script itself, here you go. alltho it is written for maya4.0 it is also running with maya7.0 which I use. you can also put the iconFiles into your local pref/icon directory good luck!
