Battery Pack upgrade or replacement for vintage RAD robot

The main battery pack prints with minimal supports.
I used nickel plated metal for the battery contact points but you can use whatever plated think metal you might have around.
I used two C cell battery holders but again depending on what you want to use for your 6 volt supply you can use what you want.
The original battery pack used four AA Ni Cad batteries.
Demo video will be up 7/11/2025 on YouTube. https://youtu.be/HhD2NvavX3Q
