Hi Davis

Thx.  I'm sure someone could come up with a jig or something that can bend
them to the right shape and then work out a method to get consistent and
reliable electrical contacts.

This is a pretty cool project.

About the battery tray, one can bend some steel wire to the dimensions
of the original contacts.

As for wear and tear, there are two main types of plastic used in these
machines: ABS and PLA.  ABS is very strong (Legos are made from it) but
inflexible.  PLA is a bit more flexible.  With either plastic, the part
should be plenty strong.
