Well I got around to finalizing the battery in the bed
To start things off in the software I used to make everything I took the battery tray, and the box, lined them up, and took the negative. I also added 4 squares in the size of some neodymium magnets that I harvested from a broken outrunner brushless motor.I had.
I then cut out the opening for the wires



After that I removed a little material from where the magnets were going, and then I took one of the magnets from the bad motor heated it up (making it worthless), and used it to press into the spaces I made so the magnets will have a firm fit.

After that I ran the wire, and installed a 3d printed grommet to cover the slightly jagged hole I cut.


And no the tray is not crooked it is perfectly straight, and the battery is in the tray crooked.

and to just show how it was ran as I zip tied the wire to the frame to keep it out of the way of the drive shafts.




I would take out the tray to put it possibly in my jeep build to replace the printed one, but I didn't feel like unscrewing the top, but when I eventually paint this, and have to disassemble it I do it then. I would have painted it last year, but stuff happened(air brush's valve breaking, stuff happening, and arthritis flareups), and when I finally had time, and the equipment to do so it was too cold already >.>
