This is a model of a mini firewall for planes like FT Tiny Trainer. Please note that it's 1mm thicker than original (as I was unsure about the strength of the plastic). It allows you to use an MT2204 motor like the one shown on the picture. Use it on your own responsibility, Flite Test recommends using plywood.

Print in strong and temperature resistant materials. Use screws supplied with the motor.

alright I hope this helps someone cause I already made 10 test prints of it
