Little Blower Fan Duct
thingiverse
If you don't need a whole assembly to mount your blower fan and instead just need a little duct to angle it. This print should just press fit in place and stay there happily because it is so light. if you feel the need you can always use a couple of dots of PVA craft glue (Elmers glue? USA?) to hold it in place and still remove it later
