stacked electronics mount allows octopus to touch motors when placed upside down

Ideally that won't happen.
Looks like the slots for the hinge are longer than they need to be for freely hinging the assembly. Thus, one possible solution is to make that smaller.
Another solution is to have a nub sticking out from the edges that would touch the motor before the PCB of the octopus would.

When the Micron is right-side-up, this isn't a problem.

Another solution is to have the mount push against the frame when it is locked in, which might require another preloaded nut.
