Wheel Chair battery holders - Panasonic LC-CA1215PZ1

For my wheel chair adaptation, I use two 12 volt batteries sitting on a shelf which kept sliding around. So I created these holders so that they don't slide or fall on tight turns.
I keyed the sides, so you can print these on any medium size printer. Left and right are marked.
The Panasonic LC-CA1215PZ1 is a very common deep cycle battery, so I hope this helps others out there. Printed and checked. They make a nice housing so your batteries don't slide around!
Let me know if you print one.
