Here is the initial design for the motor fan connector that can take 120mm fans:



As you can see it's big Printed out with a fan attached:



And on the motor:

Can you not get a bigger fan ?

Well done it looks great....and very quick...

The final design of this I've made more condensed so the fan doesn't end up too close to the chain.  It no longer sits in the 3 holes on the back of the motor, but instead slots into the 2 larger sections on the back like this to improve the airflow:



And mounted to the motor with the fan on it:



For added peace of mind there is a 3mm hole on each connector allowing you to bolt it together when hooked onto the motor.  When you do this it is staying put

I also made a longer version of the normal 90mm connector that allows the plastic heat sensor to remain in place:



Drop us a PM if you're interested in any of these, let me know which one you want.

I no I'm being cheeky can I have both with the sensors ?

Yep. When I get back ill print some out.
