Summary

I wanted a 5 cell pack in the AHI for hih speed servo movement so built one from 2/3 AA Cells.
They are laid out as shown so that the lower cell fits into the ballast area.
This leaves them higher than a standard pack so this holder allows for that to replace the stock plywood one.
0.2 layer height and 15% infil worked fine for me.
Print in the normal orientation with support.
Enjoy.
