it is a back for the ASUS ROG Ally Extreme  to offer a bit of a different look  and possibly better cooling I'm a total newbie at modeling  so it might not look pretty  atm but I did say its a WIP (work in progress) 

ps.dont  print it like in  the photos  they are only there to show what the models looks like  i will replace those pictures later when  my prints are done eventually also  probably best to use abs or petg because the Ally gets pretty warm
