Ok. I figured out how I’m going to hold all the elements in place ‘under the hood’.
First the holder:
The little dimples behind the fan screen will fit within two screw holes under the fan that I plan to use. The hole in the bottom of the holder fits around the screw that holds the deck down to the motor mount. Then there are holes to help ventilate the battery and all the elements there will be here.
Next the platform for the receiver so it doesn’t touch and short out on anything metal. The little dip was for the underside pins of the terminal block on the receiver:
The middle section is to hold the battery in place and keep it from moving around:
And the little ledge was to hold up the speaker (also using the top of the fan casing to hold it up):
This all seemed fine to me, then I realized it wouldn’t fit in front of the cab. I had to cut away where it wouldn’t be seem for the battery to stick inside the cab a little bit. I figured it would be covered up by the console/controls inside the cab so one wouldn’t see or notice it. I also had to cut out a slot to feed the wires back into the engine compartment from the cab. And because the edge of the tin plate was sharp, I had to 3d print some TPU to cover up the edge. I’m planning on re-printing it because I don’t feel it covers enough of it up. But using TPU was handy as it conformed to the shape of the hole that was cut out.
There, everything fits nice and snug, but not too snug. I think there will be enough air movement around everything to keep things from getting too hot when operating.
Now, onto wiring this all up and trying to install an on/off(charge) switch. I have an idea, now I have to find time to execute that idea. Life is creeping in again and I’ve got to take the free time I have and work on this, regardless if I mess up or not. So till the next story dumping time…keep on railroading!

and make it the way I had imagined, since each critter is unique in the makers mind. This is what I ended with:
