Pics as requested. Couple notes: The tray came apart at end of 60mph video. I used an ABS cement to put the tray together, but it didn't bond well to the plastic. I redid it w/ Gorrilla glue, but rear tray shifted during drying and backend sticks out too much from the side. Fit snug first time (see 1st pics in earlier post) and only over hung by ~2mm. Need to fix this, but, eh works for now. Pic makes the repair look worse than it is tho.
Basically the tray is the project box quartered, slimmed down to 35mm wide, and a single strip of ABS attaching all the quarters together. Thin padding foam from T2 batt tray runs the length. 2 3mm from below, now 2 3mm from top bolting all quarters down for extra strength.
Top w/ batt:
3s batt from side:

Comparing 35mm wide batt to 44mm ("1/10th scale") batt. 35mm batt is shorter and less wide but taller. Fits better on OFNA chassis IMO.
