How did you install those pc fans on a bar like that? I guess the bar is the main part, I've been trying to work out how to do the same.
I like your set up. I run a 20inchx20inch tent.
Thanks
@BermudaCower, Hi bro, they are attached using metal meccano but any small brackets would do the trick. If you look through my diaries you can see their evolution! The main part is a bit of wooden angle. Hope this helps
