...the Boxer is 10 times better than a Frankie with just a bottle swap. =) How about this way? All contacts are made out of Beryllium Copper and the square contact on 510 connector is made out of Oxygen free copper.

nice work! quick question, what size is the threading for the square copper contact? i dont really have the tooling to make a fancy oxygen free copper one from scratch, but was thinking i could get a similar effect using a copper nut with the right threading.

any idea what size would fit?
