Athearn SD9 Motor Circuit Board Mount
thingiverse
Clip-style mount to attach a small PCB to the motor of an Athearn SD9. Because the motor on the SD9 sits higher within the shell than on other locomotives (due to the three-axle trucks of the SD9 having a larger first pinion, I think), the [mount for an F7 or GP9](https://www.thingiverse.com/thing:5545083) is too tall. Though it accommodates a smaller circuit board, this mount will fit inside the shell. I've uploaded two versions. V2 is the one in the pictures. V3 has been shortened slightly to create more clearance between itself and the transparent plastic piece for the cab windows. V3 <i>should</i> work, but I'm uploading both in case it doesn't. A V4 could be improved by extending a platform over the rear flywheel to manage the harness coming from the rear truck.
