This is a custom battery terminal for fablab.ee's Makita 18V battery adapter.
This is designed to be used with 6,3mm blade connectors (red, blue).
Just crimp on the cable and push it through the hole in the terminal.
My print is a friction fit, but glue them in place just to be sure.
This won't last forever, but will do the job till my Makita 643852-2 Battery terminals arrive from china.
The author remixed this model.
