Fits pretty good, not perfect though :)

This is a great, and necessary, addition to the Battery Holder. Stops the jams! Thank you!
Thanks! Good design. Batteries (14v & 18v) fit tight and are held securely in place.
Great model! The fit is perfect on Panasonic EY batteries. I see that you linked the terminals that you used, but you mention using a small PCB that you soldered the terminals on. Could you share what PCB you purchased? (edited)
