Yes, you can check amazon/ebay or maybe even fb marketplace.
I 3d printed one, but there's some post-print work that must be done - making terminals, finding an appropriate spring for the release buttons, soldering wires between the two terminals, and then there's small hardware (the model I used calls for 3mm screws and nuts).
I haven't used it much. I found the slot that the Ridgid battery tabs go into wasn't placed quite right, but a few strokes from a file and it's better.
