Computer Fan Connectors

I needed a larger fan, and had some PC fans sitting in a box, so I made a small print that would allow me to connect them together to make a larger fan. I've currently only made up to a group of four. but I'd like to try six, so I can have a quiet window fan. I'll let you know if I ever go that route. 

I think it's fairly self explanatory. print as many as you need, comes it twos and fours. 
they poke in one side and then you'll need small screws for the backside.

The center post (fours) needs be printed in 3 piece and must be screwed together on center on the pin side.this one is a little fiddly to get together, but if you start with the center connector on the pin side of one fan and tip the fans to line up the screw holes, it works quite well. once aligned you can add screws.

I also used the twos as cable management as you can see from the photos, this worked out quite well for me. hopefully it will also do well in your use case.

if you have any questions, don't hesitate to ask, and otherwise, enjoy!
