An improved firewall for the standard size Flitetest power pod (for Spitfire, Mustang, Simple Cub, Corsair, etc).

I have included motor mount holes (1.2mm diameter, 34mm PCD).
There is a hole at the bottom to feed your XT60 connector from the ESC back out of the power pod.
The front wall is 2.6mm thick.
It has side walls to give the power pod better crash resistance (and the holes give the hot-glue extra grip).

UPDATE:

I have added two versions with [16mm x 19mm] and [19mm x 25mm] M3 mounting holes.
(If your motor wires are on the other side, then mirror the object in your slicer.)

You don't need supports if you have a part-cooling fan (PLA).

I used 0.2mm resolution, 4 top layers, 4 bottom layers, 5 shells, 15% infill and it weighs 9 grams.
