This model came out of the need for a new firewall after the one I had broke. It's not a very complicated design but gets the job done.

As for build instructions there isn't much to say expect for print, connect your motor, and glue on the plane :).

Printing tips:

Print flat with no supports and an infill of anything between 70-100%, just remember that on a firewall rock solid is not always the best because you rather break a firewall than a motor :).
