Up mini top mount fan

During PLA printing, it's necessary to remove the top panel, in order to evacuate the hottest air.
I use the released space to put an addional fan. I made a support for a 90mm fan. It takes place above the front door. I keep it in place with velcro.

The airpipe send air directly to the PLA piece.

The fan is actually plugged to an external power supply. But i designed the piece with holes and spaces for invisible wires. After the end of my printer warranty, i will use an internal 12V source and a pwm regulator to manage the airflow.
