Funtime Marble Roller System Battery w/Switch mount

This is a battery pack for the motor for the Funtime Marble Roller System lift. It can be used anywhere but the mounting plates are designed for this system.

i designed this battery holder with several ideas in mind. First, I needed to put my batteries in parallel rather than series. You can choose to do either but I needed more current not voltage. Secondly, I designed the holder so that it was versatile when it comes to connecting wires. Whether you wish to use what I have done or connect the batteries in other manners the mount shouldn't get in the way of things.

Additional Pieces:
3-way Boat Toggle Switch, I bought 50 of these. Similar to this but far cheaper.
