I found this project on Make for an automatic ball thrower for your dog, and am in the process of wrapping it up.

For power, I'm using a cordless drill battery. (Specifically, a Ryobi lithium one+ 18v battery)

I've seen a lot of projects out on the web where people just use electrical tape to wrap the leads of their wire to the battery, but this seems a bit ghetto to me.

In all of the tools, the batteries "snap" into place. Is there some kind of battery mount that snaps a cordless drill battery into place and provides some leads to solder wires to? My google-fu just results in how to rebuild a cordless drill battery, which is NOT what I am looking to do.

If you are willing to sacrifice a battery charger, you could gut the charging circuitry out of the charger housing and wire it as a battery dock.

I know this is an old post, but I found this here. Keystone BK-204 battery clips that slide right on, and then all you have to do is attach a wire.

Ultimately, what I'm looking for is this:

I'll have to find someone with a 3D printer, but that's not too much of a problem.

Thanks everybody for their suggestions!
